How to Repair PST Files on Outlook 365/2016/1013/2010/2007 in Windows 10

PST files in Outlook contain all the messages, events, and calendars that are saved on your computer. You can use this file to back up and export items from all email accounts.

Unfortunately, malware and some other factors can corrupt this file, and when users try to access Outlook it shows an error that states “Outlook PST File is not in a personal folder file” or “Unable to open Outlook PST File”. It can be a headache and can disturb the workflow. Luckily, it is not a problem without solutions. All the solutions are tested involved in this article.

Let’s take a look at how you can repair the PST files on Outlook.

What are the main reasons for Outlook PST being corrupt?

PST files can get corrupted because of several reasons, but some types are more frequent than others. These include:

Hardware Failure

Network and power-related problems all come under hardware failure. Networking issues are more common in settings where PST files are accessed remotely. The problem with interface cards, network hubs, servers, and routers can make the file prone to corruption. Furthermore, if the system experiences a power outage while users try to access, the PST file can also corrupt.

Data Recovery Tools

Some data recovery tools can never return all the files, and improper or wrong file recovery can corrupt the PST file. It is because the recovered version can replace the recent PST file even though it is incomplete. And if the tool makes a complete recovery, replacing it with the recent file will lead to loss of stored data.

Malware Attacks

Malware can delete and modify the PST file which leads to corruption. Some viruses are designed to specifically target these files, so exposure to any of these will damage the PST file. These viruses include Worm ExploreZip, Stages Virus, Blebla, and Melissa. But the installation of a quality anti-virus can prevent this form of corruption.

Incorrect Shutdown Procedure

No matter how fast a system is, a certain amount of time goes into saving the data on the PST file. Shutting the Outlook Window or the computer while the process is ongoing can corrupt the file. You must always save all the changes that have been made to Outlook and then exit properly.

Furthermore, stopping Outlook from the Task Manager can also cause this problem. So, if the application stops responding, it is better to wait a few minutes before shutting it down from the Task Manager.

Problems with Outlook Versions

The older versions of Outlook, like 97-2002, are more prone to corruption of PST files because of a fundamental flaw. Since this version uses ANSI code, and it automatically becomes corrupted if the size of the file exceeds 2GB. Outlook itself and some third-party applications offer solutions to increase the storage size, but it is better to use newer versions instead.

All the Outlook versions, including 2003 and those released afterward, use Unicode, which can store up to 20GB. Switching to newer versions can prevent this type of corruption.

What are the common types of PST corruption?

PST corruption can manifest in several errors, but the most common of them include:

Inability To Locate PST File

If the PST file of a particular account is not available in the folder, it will show an error that states, “The file xyz.pst is not a personal folders file” or “The file xyz.pst could not be found.”

Broken PST File

If malware damages the PST file, it will show errors such as “Cannot Expand the folder”, “The set of folders cannot be opened,” or “Can’t move the item. It was either already moved or deleted.”

Network Error

Sometimes Outlook cannot access the PST files because of a problem with the network and shows errors like “xyz.pst can not be accessed - 0x80040116” or “File xyz.pst could not be accessed. Data error”.
