How to Repair Outlook PST File in Windows 11

August 06, 2026

Microsoft Outlook saves emails, contacts, calendar items, tasks, notes, and all other mailbox data in a PST file; if the file becomes corrupted then Outlook might stop responding, fail to open, show error messages, or stop you from accessing your important emails. Fortunately, Windows 11 users can have damaged PST files repaired by using the utility that is built into Microsoft or by using a professional product such as the Shoviv Outlook PST Repair Tool.

The following guide will discuss the usual reasons for PST corruption and the most effective methods of repairing Outlook PST files on Windows 11.

What causes a PST file to become corrupted?

A PST file can become corrupted for several reasons, including:

* Sudden system shutdowns or power failures
* Large or oversized PST files
* Hard drive errors or bad sectors
* Malware or virus attacks
* Improper Outlook shutdown
* Software conflicts or Outlook crashes
* Network interruptions while accessing PST files

If you know these causes, you can avoid corruption in the future.

Method 1: Use SCANPST.EXE to repair the PST file

With Outlook, Microsoft provides a free program known as the Inbox Repair Tool, which is capable of fixing minor corruption of PST files.

How to use SCANPST.EXE

1. Close Microsoft Outlook.
2. Find  SCANPST.EXE in the folder where Microsoft Office is installed.
3. Launch the utility.
4. Look through the files and choose the one that is corrupted.
5. Click Start to begin the scan of the file.
6. When errors are found, you should click on Repair.
7. Stay until the repair process is completed.
8. Open Outlook and check that the mailbox has been repaired.

Although it is effective in handling minor problems, SCANPST has difficulty dealing with severely corrupted or very large PST files.
