Methods to Fix Damaged Outlook Personal Folder (PST) File

You can try restoring the PST file from backup. But if the backup is not available, use the below-mentioned methods to repair damaged Outlook Personal Folder File:


Method 1 – Use Microsoft Built-in Repair Utility

Microsoft provides a built-in repair utility, called the ‘Inbox Repair Tool’ or ‘Scanpst.exe’, to diagnose and fix corruption errors in a PST file.

NOTE: Before running the Inbox Repair Tool, make sure to close your Outlook application and back up the Outlook Data File (.pst) you want to repair.

Follow these steps to repair corrupt .pst file by using the Inbox Repair Tool:

Step 1: Browse to any of these locations:

Outlook 2019: C:\Program Files (x86)\Microsoft Office\root\Office16

Outlook 2016: C:\Program Files (x86)\Microsoft Office\root\Office16

Outlook 2013: C:\Program Files (x86)\Microsoft Office\Office15

Outlook 2010: C:\Program Files (x86)\Microsoft Office\Office14

Outlook 2007: C:\Program Files (x86)\Microsoft Office\Office12

NOTE: If Scanpst.exe is missing, make sure that the ‘Show hidden files and folders’ setting is enabled in your Folder Options. If you still cannot find the file, try repairing Office programs.

Step 2: Double-click SCANPST.

Step 3: In Microsoft Inbox Repair dialog box, click Browse to select the PST you want to repair.

NOTE: If you are not aware of Outlook PST file location, open the File Explorer window and type the command: %appdata%\Microsoft\Outlook.

Step 4: Click Start to initiate the scan.

NOTE: The scanning process may take some time to complete, depending on the PST file size.

Step 5: If the scan finds any errors in the file, click Repair to fix those errors.

Step 6: Click OK when the repair process completes.

  • It might fail to repair a severely corrupt or damaged file.
  • You may need to run ‘Scanpst.exe’ multiple times to fix the damaged file.
  • It does not support recovery from password-protected file.
  • It may freeze in the middle of the repair process or return unexpected errors.
