The Polestar 5 is an 884hp fastback sedan that should make Porsche nervous

The Polestar 5 is an 884hp fastback sedan that should make Porsche nervous

It’s been five years since Polestar first introduced the Precept, a concept car that the electric automaker described as “a manifesto of things to come; a declaration.” Well, come they have, because today Polestar finally revealed the production car that’s based on this manifesto: the Polestar 5.

And wow, these specs: up to 460 miles of range, 800-volt architecture for ultra-fast charging, 884 horsepower, 0–60mph in an oomph-inducing 3.1 seconds for the Performance trim. It certainly makes those five years feel like worth the wait.

In final form, the Polestar 5 is an absolutely stunning fastback sedan with dramatic proportions that are sized similarly to the Porsche Panamera. The 5 will be built on a bespoke supercar-like bonded aluminum platform that’s was developed at Polestar’s own facility in England. And like the Polestar 4, it lacks a rear window, relying instead on a high-definition rearview camera.

There’s a lot more, so let’s dig into it.

At launch, there will be two versions of the Polestar 5: a Dual Motor trim with 748hp (550kW), 599lb-ft of torque (812 Newton-meters), and a 0–60mph time of 3.8 seconds; and a Performance package with 884hp (650kW), 749lb-ft (1,015Nm) of torque, and 0–60mph acceleration in 3.1 seconds. Both versions are speed-limited to a maximum of 155mph — seemingly in the spirit of former parent company Volvo’s safety maxim of limiting vehicle max speed to 112mph.

The 800-volt architecture is new to Polestar, and should enable 350kW charging when plugged into a suitable charger. That means 10–80 percent charging in “as little” as 22 minutes, the company says. Owners can expect a WLTP estimated range of 670km (416 miles) for the Dual Motor trim and 565km (351 miles) for the Performance one.

The Polestar 5’s battery contains 112kWh of energy, 106kWh of which is usable. The SK One-supplied NMC (nickel cobalt manganese) pack consists of eight modules with 192 cells. And its design forms part of the 5’s steel structure, which Polestar says brings safety benefits.

The Polestar 5 is built on the company’s Polestar Performance Architecture (PPA), which uses a bespoke, hot-cured aluminum structure for improved weight and rigidity. That frame consists of 13 percent recycled aluminum and 83 percent aluminum from smelters (no word on the remaining 4 percent), which helps lower the 5’s carbon footprint when compared to standard sourcing.

(Keep in mind that Polestar has positioned itself as one of the few automotive startups that still gives a shit about climate change. The company’s CEO recently used his keynote at the IAA Mobility conference in Munich, where the Polestar 5 will make its debut, to urge EU leaders to stick to their strict zero-emission goals.)

The Performance variant is slated to have a sport-tuned suspension with semi-active dampers. There are also bespoke Michelin tires, designed specifically for the Polestar 5, ranging from 20 to 22 inches depending on the trim level.

Inside, you’ll find a 14.5-inch portrait display alongside a 9-inch instrument cluster behind the steering wheel. To cut down on distractions, there will be a 9.5-inch heads-up display projected on the windshield. And a driver-monitoring camera makes sure the driver keeps their eyes on the road while the driver assist system is engaged.

The Performance variant is slated to have a sport-tuned suspension with semi-active dampers.

The front fascia features Polestar’s SmartZone, which consists of many of the vehicles’ sensors, like radar and the front parking camera. In total, the Polestar 5 has 11 vision cameras, one driver monitoring camera, one mid-range radar, and 12 ultrasonic sensors. (Unlike the Polestar 3 and 4, the 5 won’t feature a lidar sensor.) The vehicle also uses interior radars to detect the number, position, and type of occupants to “deploy the correct safety measures in the event of an accident.”

There’s a lot of high-end brand names scattered throughout this announcement: Brembo for braking, Bowers & Wilkins for a premium audio system, and Bridge of Weir nappa leather as an optional interior. The driver-assist system is powered by Mobileye, while the infotainment system runs on Google’s embedded Android software.

While designed as a four-seater, the rear arm rest can be lifted to accommodate a fifth passenger. Polestar cut out a space in the battery, known as the foot garage, behind the front seats to give occupants an extra foot of space for a more natural seating position.

Polestar didn’t reveal a launch date or starting price for the 5, only to say they are coming soon. Suffice it to say it won’t be cheap. The Performance version of the grand tourer is expected to start somewhere north of $100,000 in North America.

The company has had a strong sales year so far, thanks to some deep discounts, including one geared toward converting former Tesla owners. The company makes the Polestar 2 electric fastback, the Polestar 3 electric SUV, and the Polestar 4 electric SUV coupe.

Tariffs are sure to take a toll on the Geely-owned, Swedish-designed company’s future. Polestar manufactures in the US and China, and plans to make the Polestar 4 in South Korea in the second half of 2025. It hasn’t said where the 5 will be built, so that will be one to watch.

But despite these challenges, Polestar is charging ahead. First shown last spring as the O2 concept, the Polestar 6 will be the brand’s next flagship model, taking the form of a two-door sports car with a convertible roof. And when the 6 goes on sale (presumably in 2026), it will use the same architecture and powertrains as the Polestar 5.

Security researchers have confirmed that a European politician had his phone hacked with the Pegasus spyware while serving on an investigatory committee probing abuses of the notorious surveillance tool. This has reigniting fresh controversy over governments abusing spyware to collect information about their critics.

The researchers at the University of Toronto’s digital rights unit The Citizen Lab say the confirmed phone hacking of Greek journalist and former politician Stelios Kouloglou during 2022 and 2023 marks the first time that a member of the European Parliament’s PEGA committee, tasked with investigating phone spyware attacks by European governments, has been publicly identified as a victim of spyware.

Kouloglou told TechCrunch in a phone call that the deliberate compromise of his phone was “reckless.” One serving European lawmaker described the hacking of Kouloglou’s phone as a “direct attack on the rule of law,” and called on the European Commission to take concrete action by imposing strict limits on the use of spyware across the 27 member-state bloc.

While spyware attacks on lawmakers are rare, the timing and targeting of a committee investigator by way of the very spyware under his investigation suggests an intense focus on the committee’s inner workings ahead of a widely anticipated report detailing its findings. The hacks open fresh questions about how governments use spyware ostensibly needed for identifying serious crime, but then caught spying on the communications of journalists, lawmakers, and critics.

Citizen Lab’s researchers did not attribute the phone hacking to a specific country, but said that the government customer used the same Pegasus-loaded email address that was used in a previous campaign that hacked into the phones of journalists across Europe. The customer’s identity is not known, but the reuse of the same attacking email address implies that the customer had NSO Group’s authorization to use its Pegasus spyware to snoop on phones across multiple countries in Europe.

A spokesperson for the European Commission did not respond to TechCrunch’s request for comment. NSO Group also did not respond to a request for comment about the Citizen Lab report prior to publication.

In its report out Friday, Citizen Lab said Kouloglou was hacked in October 2022 and at least twice during March 2023 using an exploit that compromised a security vulnerability in Apple’s iPhone software. This vulnerability had been patched but the fix was not yet installed on Kouloglou’s phone. The exploit was a “zero-click” bug, meaning the spyware broke in and stole his data without needing any interaction on his part.

The bug abused a previously discovered flaw in Apple’s smart home software used in iPhones. It allowed the spyware to grab private data from Kouloglou’s phone without his knowledge, such as his text messages and other correspondence, location data, and photos.

The timing of the October 2022 hack coincides with intense discussions over email and text message throughout October and November 2022, ahead of the delivery of a first draft describing spyware abuses focusing in Cyprus, Greece, Hungary, Poland, and Spain. 

The hack also lines up at the exact time that Kouloglou was in the hospital at the time for a pre-scheduled surgery, which may have allowed the spyware operators to listen in to ambient audio discussing his healthcare or other conversations he had with visitors at the time.

Months later on March 6 and 7, Citizen Lab said Kouloglou’s phone was hacked again by the same Pegasus operator while Kouloglou traveled from Athens to Brussels, during a period of committee hearings and months prior to the committee finalizing and adopting their written draft report.

In a call, Kouloglou told TechCrunch that he didn’t know why he was specifically targeted but that he believes it was due to his work on the European Parliament’s committee investigating Pegasus abuses.

He described anger when he learned that his phone had been hacked. 

“You realize that all of your personal data [was taken] — not all the professional exchanges or messages with ministers — but also the very private things, like the happy moments and the sad moments,” he told TechCrunch.

Kouloglou said he plans to sue NSO Group, the Israeli-headquartered spyware maker. NSO remains largely banned from use in the United States following a Biden-era executive order that outlawed the government’s use of spyware that could violate people’s human rights. 

Last year, the spyware maker confirmed an unnamed American investment group funneled tens of millions of dollars into the company, likely as part of an effort to rehabilitate NSO’s beleaguered brand associated with enabling human rights abuses.

Kouloglou said he was going public with his story “for democracy, human rights, and the fight against corruption.”

“Corruption concerns everybody,” he said.

ScanPST. Since it ships with Outlook, it’s usually the first recommendation you’ll find. And to be fair, it does work in some situations. But a lot of times, it either simply refuses to repair the file, gets stuck midway through the process, or successfully repairs the mailbox only for important emails and folders to go missing afterward. That’s because the tool was made to fix minor errors, not to recover severely corrupted mailboxes. That’s why several third-party Outlook PST repair tools now exist that claim to mend Outlook for you. Before looking at these alternatives, though, it’s better to know why PST files become corrupted in the first place.

Why a PST File Gets Corrupted & Reasons

For the uninitiated, a PST file is essentially a database containing all your emails and important attachments. Whenever you ask POP3-configured Outlook for a particular document, it retrieves it from a local saved PST file, making it a fundamental component. Like any database, these files rely on their internal structure remaining intact. If that structure is damaged, Outlook cannot access your information, and there can be plenty of reasons for that.

  • Large PST files: Bigger Outlook data files are more likely to become corrupted, especially as they approach Microsoft’s recommended size limits.
  • Unexpected shutdowns: Power outages, system crashes, or force-closing Outlook while it’s saving data can damage the PST file.
  • Storage drive issues: Failing hard drives, bad sectors, or insufficient disk space can lead to file corruption.
  • Using network drives: Microsoft advises against storing PST files on network locations, as unstable connections can interrupt read/write operations.
  • Faulty add-ins or malware: Buggy Outlook add-ins, malware, or third-party utilities can also corrupt PST files over time.

Why ScanPST Fails to Restore PST Data?

The reasons are plenty, and that’s exactly why Microsoft bundles its own repair tool, ScanPST, with Outlook. In theory, it scans the internal structure and attempts to repair damaged indexes and references so Outlook can open the file again.

However, there is a problem. If ScanPST encounters mailbox items it can’t validate, it often removes them instead of rebuilding them.

Why ScanPST Fails to Repair Corrupt PST Files — and the Best Alternatives 
	
Whether you like using it or not, Microsoft Outlook is the lifeblood of almost every corporation in 2026. And there’s a good chance your work emails, meetings, and attachments all live inside the email client. Sadly, as with many of Microsoft’s worsening services these days, Outlook can also run into trouble, with the most common problem being an error that says your data file can’t be accessed. This frustrating issue has been around for a long time, and yet Microsoft still hasn’t completely fixed it.



Instead, Microsoft offers its own Inbox Repair Tool, better known as ScanPST. Since it ships with Outlook, it’s usually the first recommendation you’ll find. And to be fair, it does work in some situations. But a lot of times, it either simply refuses to repair the file, gets stuck midway through the process, or successfully repairs the mailbox only for important emails and folders to go missing afterward. That’s because the tool was made to fix minor errors, not to recover severely corrupted mailboxes. That’s why several third-party Outlook PST repair tools now exist that claim to mend Outlook for you. Before looking at these alternatives, though, it’s better to know why PST files become corrupted in the first place.



Why a PST File Gets Corrupted & Reasons



For the uninitiated, a PST file is essentially a database containing all your emails and important attachments. Whenever you ask POP3-configured Outlook for a particular document, it retrieves it from a local saved PST file, making it a fundamental component. Like any database, these files rely on their internal structure remaining intact. If that structure is damaged, Outlook cannot access your information, and there can be plenty of reasons for that.




Large PST files: Bigger Outlook data files are more likely to become corrupted, especially as they approach Microsoft’s recommended size limits.



Unexpected shutdowns: Power outages, system crashes, or force-closing Outlook while it’s saving data can damage the PST file.



Storage drive issues: Failing hard drives, bad sectors, or insufficient disk space can lead to file corruption.

Faulty add-ins or malware: Buggy Outlook add-ins, malware, or third-party utilities can also corrupt PST files over time.




Why ScanPST Fails to Restore PST Data?



The reasons are plenty, and that’s exactly why Microsoft bundles its own repair tool, ScanPST, with Outlook. In theory, it scans the internal structure and attempts to repair damaged indexes and references so Outlook can open the file again. 



However, there is a problem. If ScanPST encounters mailbox items it can’t validate, it often removes them instead of rebuilding them.



How To Repair A Corrupt PST File Without ScanPST







Since we all would dearly love to get important files and attachments back, the first thing you should do is create a copy of the original PST file. Working directly on the only copy of your mailbox is risky because every repair attempt changes the database. So keep the original intact. Next, if you’re dealing with smaller PST files or working on managed office computers where software installation isn’t possible, an online PST repair service would be your best bet. One of the safer options is the Stellar Online PST Repair service. It works online, and Outlook itself doesn’t even need to be present on the system. It supports PST files from Outlook 2003 through Outlook 2024, including both ANSI and Unicode formats, and lets you preview mailbox folders and recovered item counts before downloading the repaired file.



Unlike ScanPST, the service’s main purpose is to repair and recover your files. And if your PST file is less than 500MB, you don’t even have to pay anything. The premium version increases that limit to 5GB. The only requirement is a stable connection, which shouldn’t be a problem in a corporate office.



Repair A Corrupt PST File Using Stellar Online PST Repair



Before we begin, it’s really important to back up your original PST file. No matter how great a tool is, Microsoft recommends keeping a copy before attempting any repair, as the recovery process modifies the mailbox structure. Once done:




Close Microsoft Outlook completely. Even if you’ve closed the Outlook window, it can continue running in the background, keeping the PST file locked.



Open Stellar Online PST Repair. Since the tool runs entirely in your browser, there’s nothing to install, and Outlook doesn’t even need to be present on your PC.



Upload your corrupt PST file. Select the mailbox you want to repair and upload it to the service.



Preview the recovered mailbox. Before downloading anything, browse through your recovered data. Check important folders like Inbox, Sent Items, Deleted Items, Archive, Contacts, Calendar, Tasks, and any custom folders you created.



Download the repaired PST file. Once you’re satisfied with the preview, download the repaired mailbox.



Open the repaired PST in Outlook. In Outlook, head to File → Open & Export → Open Outlook Data File, then select the repaired PST. Verify all information. 




When to Use a Desktop PST Repair Tool Instead



As good as browser-based repair services are, they can only be used for quick fixes. Large mailboxes containing years’ worth of emails can take a long time to upload, and severe corruption is often beyond what an online service is designed to handle. In that case, the Stellar Repair for Outlook app makes much more sense. It has the same bells and whistles, like the ability to preview recoverable emails in detail, such as emails, attachments, contacts, calendars, and other important information, but processes everything locally, so your mailbox never leaves your computer.



It also doesn’t impose practical file-size limitations, supports encrypted and password-protected PST files, and allows recovered data to be saved not only as a new PST but also in formats like MSG, EML, HTML, PDF, and others. For businesses or IT administrators, the Technician edition can even export recovered mailboxes directly to Microsoft 365 or Exchange, making it easier to restore users without additional migration steps.

Conclusion



ScanPST remains a useful first step whenever Outlook reports a damaged PST file. It’s free, already installed alongside Outlook, and can often repair minor hiccups. However, it’s not the golden child. It fails to retain your precious files. If you don’t want that to happen, it makes sense to consider alternatives that focus on recovering mailbox data. An online repair service is often enough for smaller files and one-time repairs, while a dedicated desktop recovery tool offers more flexibility for larger or business-critical mailboxes.



Frequently Asked Questions (FAQs)



Where is ScanPST.exe located? The exact location depends on your Outlook version and installation method, but ScanPST is typically stored inside the Microsoft Office installation folder under Program Files.  Does ScanPST delete emails? Yes. If ScanPST comes across mailbox items that it cannot validate during the repair process, those items may be removed from the repaired PST file.  Can ScanPST repair large PST files? In theory, yes. But performance tends to decline as file sizes grow. Severe corruption or very large mailboxes often require more specialized recovery software.  How do I repair a PST file without losing data? Always create a copy of the original PST before attempting repairs. If ScanPST doesn’t resolve the issue, using a recovery tool that rebuilds mailbox data rather than deleting damaged items is a safer approach.  Can I repair a PST file without installing software? Absolutely. Browser-based repair services allow you to upload supported PST files, preview recoverable mailbox data, and download the repaired file without installing Outlook or additional software.

Working directly on the only copy of your mailbox is risky because every repair attempt changes the database. So keep the original intact. Next, if you’re dealing with smaller PST files or working on managed office computers where software installation isn’t possible, an online PST repair service would be your best bet. One of the safer options is the Stellar Online PST Repair service. It works online, and Outlook itself doesn’t even need to be present on the system. It supports PST files from Outlook 2003 through Outlook 2024, including both ANSI and Unicode formats, and lets you preview mailbox folders and recovered item counts before downloading the repaired file.

Unlike ScanPST, the service’s main purpose is to repair and recover your files. And if your PST file is less than 500MB, you don’t even have to pay anything. The premium version increases that limit to 5GB. The only requirement is a stable connection, which shouldn’t be a problem in a corporate office.

Repair A Corrupt PST File Using Stellar Online PST Repair

Before we begin, it’s really important to back up your original PST file. No matter how great a tool is, Microsoft recommends keeping a copy before attempting any repair, as the recovery process modifies the mailbox structure. Once done:

  1. Close Microsoft Outlook completely. Even if you’ve closed the Outlook window, it can continue running in the background, keeping the PST file locked.
  2. Open Stellar Online PST Repair. Since the tool runs entirely in your browser, there’s nothing to install, and Outlook doesn’t even need to be present on your PC.

    Upload files button on the Stellar ScanPST repair site

  3. Upload your corrupt PST file. Select the mailbox you want to repair and upload it to the service.

    Start Repair button

  4. Preview the recovered mailbox. Before downloading anything, browse through your recovered data. Check important folders like Inbox, Sent Items, Deleted Items, Archive, Contacts, Calendar, Tasks, and any custom folders you created.

    Preview button on the website

  5. Download the repaired PST file. Once you’re satisfied with the preview, download the repaired mailbox.
  6. Open the repaired PST in Outlook. In Outlook, head to File → Open & Export → Open Outlook Data File, then select the repaired PST. Verify all information.

When to Use a Desktop PST Repair Tool Instead

As good as browser-based repair services are, they can only be used for quick fixes. Large mailboxes containing years’ worth of emails can take a long time to upload, and severe corruption is often beyond what an online service is designed to handle. In that case, the Stellar Repair for Outlook app makes much more sense. It has the same bells and whistles, like the ability to preview recoverable emails in detail, such as emails, attachments, contacts, calendars, and other important information, but processes everything locally, so your mailbox never leaves your computer.

It also doesn’t impose practical file-size limitations, supports encrypted and password-protected PST files, and allows recovered data to be saved not only as a new PST but also in formats like MSG, EML, HTML, PDF, and others. For businesses or IT administrators, the Technician edition can even export recovered mailboxes directly to Microsoft 365 or Exchange, making it easier to restore users without additional migration steps.

Conclusion

ScanPST remains a useful first step whenever Outlook reports a damaged PST file. It’s free, already installed alongside Outlook, and can often repair minor hiccups. However, it’s not the golden child. It fails to retain your precious files. If you don’t want that to happen, it makes sense to consider alternatives that focus on recovering mailbox data. An online repair service is often enough for smaller files and one-time repairs, while a dedicated desktop recovery tool offers more flexibility for larger or business-critical mailboxes.

Frequently Asked Questions (FAQs)

Where is ScanPST.exe located?

The exact location depends on your Outlook version and installation method, but ScanPST is typically stored inside the Microsoft Office installation folder under Program Files.

Does ScanPST delete emails?

Yes. If ScanPST comes across mailbox items that it cannot validate during the repair process, those items may be removed from the repaired PST file.

Can ScanPST repair large PST files?

In theory, yes. But performance tends to decline as file sizes grow. Severe corruption or very large mailboxes often require more specialized recovery software.

How do I repair a PST file without losing data?

Always create a copy of the original PST before attempting repairs. If ScanPST doesn’t resolve the issue, using a recovery tool that rebuilds mailbox data rather than deleting damaged items is a safer approach.

Can I repair a PST file without installing software?

Absolutely. Browser-based repair services allow you to upload supported PST files, preview recoverable mailbox data, and download the repaired file without installing Outlook or additional software.

Whether you like using it or not, Microsoft Outlook is the lifeblood of almost every corporation in 2026. And there’s a good chance your work emails, meetings, and attachments all live inside the email client. Sadly, as with many of Microsoft’s worsening services these days, Outlook can also run into trouble, with the most common problem being an error that says your data file can’t be accessed. This frustrating issue has been around for a long time, and yet Microsoft still hasn’t completely fixed it.



Instead, Microsoft offers its own Inbox Repair Tool, better known as ScanPST. Since it ships with Outlook, it’s usually the first recommendation you’ll find. And to be fair, it does work in some situations. But a lot of times, it either simply refuses to repair the file, gets stuck midway through the process, or successfully repairs the mailbox only for important emails and folders to go missing afterward. That’s because the tool was made to fix minor errors, not to recover severely corrupted mailboxes. That’s why several third-party Outlook PST repair tools now exist that claim to mend Outlook for you. Before looking at these alternatives, though, it’s better to know why PST files become corrupted in the first place.



Why a PST File Gets Corrupted & Reasons



For the uninitiated, a PST file is essentially a database containing all your emails and important attachments. Whenever you ask POP3-configured Outlook for a particular document, it retrieves it from a local saved PST file, making it a fundamental component. Like any database, these files rely on their internal structure remaining intact. If that structure is damaged, Outlook cannot access your information, and there can be plenty of reasons for that.




Large PST files: Bigger Outlook data files are more likely to become corrupted, especially as they approach Microsoft’s recommended size limits.



Unexpected shutdowns: Power outages, system crashes, or force-closing Outlook while it’s saving data can damage the PST file.



Storage drive issues: Failing hard drives, bad sectors, or insufficient disk space can lead to file corruption.



Using network drives: Microsoft advises against storing PST files on network locations, as unstable connections can interrupt read/write operations.



Faulty add-ins or malware: Buggy Outlook add-ins, malware, or third-party utilities can also corrupt PST files over time.




Why ScanPST Fails to Restore PST Data?



The reasons are plenty, and that’s exactly why Microsoft bundles its own repair tool, ScanPST, with Outlook. In theory, it scans the internal structure and attempts to repair damaged indexes and references so Outlook can open the file again. 



However, there is a problem. If ScanPST encounters mailbox items it can’t validate, it often removes them instead of rebuilding them.

Next, if you’re dealing with smaller PST files or working on managed office computers where software installation isn’t possible, an online PST repair service would be your best bet. One of the safer options is the Stellar Online PST Repair service. It works online, and Outlook itself doesn’t even need to be present on the system. It supports PST files from Outlook 2003 through Outlook 2024, including both ANSI and Unicode formats, and lets you preview mailbox folders and recovered item counts before downloading the repaired file.



Unlike ScanPST, the service’s main purpose is to repair and recover your files. And if your PST file is less than 500MB, you don’t even have to pay anything. The premium version increases that limit to 5GB. The only requirement is a stable connection, which shouldn’t be a problem in a corporate office.



Repair A Corrupt PST File Using Stellar Online PST Repair



Before we begin, it’s really important to back up your original PST file. No matter how great a tool is, Microsoft recommends keeping a copy before attempting any repair, as the recovery process modifies the mailbox structure. Once done:




Close Microsoft Outlook completely. Even if you’ve closed the Outlook window, it can continue running in the background, keeping the PST file locked.



Open Stellar Online PST Repair. Since the tool runs entirely in your browser, there’s nothing to install, and Outlook doesn’t even need to be present on your PC.



Upload your corrupt PST file. Select the mailbox you want to repair and upload it to the service.



Preview the recovered mailbox. Before downloading anything, browse through your recovered data. Check important folders like Inbox, Sent Items, Deleted Items, Archive, Contacts, Calendar, Tasks, and any custom folders you created.



Download the repaired PST file. Once you’re satisfied with the preview, download the repaired mailbox.



Open the repaired PST in Outlook. In Outlook, head to File → Open & Export → Open Outlook Data File, then select the repaired PST. Verify all information. 




When to Use a Desktop PST Repair Tool Instead



As good as browser-based repair services are, they can only be used for quick fixes. Large mailboxes containing years’ worth of emails can take a long time to upload, and severe corruption is often beyond what an online service is designed to handle. In that case, the Stellar Repair for Outlook app makes much more sense. It has the same bells and whistles, like the ability to preview recoverable emails in detail, such as emails, attachments, contacts, calendars, and other important information, but processes everything locally, so your mailbox never leaves your computer.



It also doesn’t impose practical file-size limitations, supports encrypted and password-protected PST files, and allows recovered data to be saved not only as a new PST but also in formats like MSG, EML, HTML, PDF, and others. For businesses or IT administrators, the Technician edition can even export recovered mailboxes directly to Microsoft 365 or Exchange, making it easier to restore users without additional migration steps.

Conclusion



ScanPST remains a useful first step whenever Outlook reports a damaged PST file. It’s free, already installed alongside Outlook, and can often repair minor hiccups. However, it’s not the golden child. It fails to retain your precious files. If you don’t want that to happen, it makes sense to consider alternatives that focus on recovering mailbox data. An online repair service is often enough for smaller files and one-time repairs, while a dedicated desktop recovery tool offers more flexibility for larger or business-critical mailboxes.



Frequently Asked Questions (FAQs)



Where is ScanPST.exe located? The exact location depends on your Outlook version and installation method, but ScanPST is typically stored inside the Microsoft Office installation folder under Program Files.  Does ScanPST delete emails? Yes. If ScanPST comes across mailbox items that it cannot validate during the repair process, those items may be removed from the repaired PST file.  Can ScanPST repair large PST files? In theory, yes. But performance tends to decline as file sizes grow. Severe corruption or very large mailboxes often require more specialized recovery software.  How do I repair a PST file without losing data? Always create a copy of the original PST before attempting repairs. If ScanPST doesn’t resolve the issue, using a recovery tool that rebuilds mailbox data rather than deleting damaged items is a safer approach.  Can I repair a PST file without installing software? Absolutely. Browser-based repair services allow you to upload supported PST files, preview recoverable mailbox data, and download the repaired file without installing Outlook or additional software.
