Why and When to Use a PST Repair Tool?

Outlook, as we all know, is part of the Microsoft Office Suite (together with Word, Excel, PowerPoint, Access, etc.). No matter what types of computer you hold, you probably use Outlook a lot to manage personal information. While it's a very convenient and efficient productivity tool, things can go wrong with Outlook just like many other applications.

Maybe Outlook got terminated unexpectedly due to computer power failure; maybe the software crashed due to a bug (yes, it happens), or even worse some viruses or malware attacked your computer and affected all applications you installed. All these reasons might corrupt or damage your Outlook .pst file.

Typical symptoms of such file corruption include (but not limited to): error messages like "the file couldn't be found", ".pst could be accessed - 0x80040116", "the file or directory is corrupted or unreadable". The Outlook application can't be opened, or runs very slow and crash more often, and other issues.

If any of the situations hit you, it's time to fix the file to restore your personal information. Also, you'd better act as soon as possible in order not to make the situation worse.

Outlook PST Repair Software: What to Look For

Disclaimer: so far there are no industry standards to evaluate the performance of a particular third-party software. The factors we choose as seen below are mostly based on 1) our own experience in using each program and 2) the information provided by each developer/owner and 3) the expertise of the Outlook experts with whom we consult. As such, the criteria and recommendations we come up with are our own opinions.

  • Security: every third-party software installed on a Windows PC should not contain viruses or malicious processes. We test this by downloading and uploading the .exe file to Comodo File Analysis Center. Once it's diagnosed to be clean and risk-free, we install the app for further evaluation.
  • Repair Quality: Good pst repair software should include features or functions to handle different kinds of Outlook PST file damage or corruption scenarios, and recover as many types of files as possible. Also, since every such program involves a scanning procedure, it's ideal that the process is time-efficient. Most of us don't want to wait two hours simply watching the scanning bars move at snail speed.
  • Compatibility: it's also important that such software supports all Outlook versions available such as 2003, 2007, 2010, 2013 & 2016. Also, the program can run under major Windows operating systems like Windows XP, 7, 8, 10.
  • Help & Support: fixing a broken/corrupt pst file may require you to possess a certain level of technical skills. A great pst repair tool should have an easy-to-use software interface (UI/UX), provide sufficient instructions or tutorials to avoid any confusions, and be able to reach out to if users have any questions.

The Best PST Repair Software: Our Recommendations

Please note: all the programs below have been tested by our team, and they are all virus-free and malware-free. Feel free to download and install on your computer.

Microsoft's Outlook Inbox Repair Tool

Also known as ScanPST or Scanpst.exe, The Inbox Repair Tool is built in on your computer when you install the Microsoft Outlook application. While it's not really the tool, you will use to fix a corrupt/damaged PST file, but it usually works well for smaller issues. Therefore, it's the first tool we recommend to use if you meet any Outlook issues. It's free and easy to use. Learn more from this MS support article. If ScanPST doesn't fix the problem you are facing (most likely it won't), turn to the following software.

Stellar Outlook PST Repair

It's the most robust and comprehensive solution out there, based on our test. Stellar Repair outperforms other alternatives because of its high repair rate. Not only it can scan, repair a corrupt PST file and restore all types of content (emails, attachments, calendars, contacts, tasks, notes, journals, etc.), but you can also use it to quickly re-import all emails back into MS Outlook from the new PST file it generates. In short, we highly recommend this software. It supports all MS Outlook versions and is compatible with major Windows OS.

Remo Repair Outlook PST

Remo is another excellent option when ScanPST.exe fails. The software incorporates non-destructive mechanism during the entire scanning and fixing process; it won't alter your source PST file, so it's extremely safe to use. Also, the program can handle a PST file that is more than 2GB in size which many other tools don't support. Remo can be run under any Windows-based PCs and supports Outlook 2003, 2007, 2010, 2013 & 2016.

Final tips

While these PST repair tools are great in fixing and recovering your lost Outlook content, it's not 100% guaranteed that you'll be able to restore all you want. Plus, a decent amount of time and energy need to be input. Therefore, we encourage you to have a habit of backing up all digital data that is important to you — Outlook files included. Remember, backup is king in the digital age, and it will save you lots of headaches.
