A PST (Personal Storage Table) file stores your emails, contacts, calendars, and other mailbox data in Microsoft Outlook. PST files can get corrupted due to sudden shutdowns, oversized files, virus attacks, or faulty add-ins.

Signs of a Corrupt PST File​

  • Outlook won’t open or crashes frequently
  • Error messages while opening PST
  • Missing emails or folders
  • Outlook freezes while loading mailbox
Method 1: Repair PST Using Inbox Repair Tool (ScanPST.exe)

Microsoft provides a free built-in repair utility called Inbox Repair Tool (ScanPST.exe).

Steps:
  • Close Outlook completely.
  • Locate SCANPST.EXE on your system (usually inside the Outlook installation folder).
  • Double-click ScanPST.exe.
  • Click Browse and select your corrupted PST file.
  • Click Start to begin scanning.
  • If errors are found, click Repair.
  • Once done, reopen Outlook and check your mailbox.
💡 Tip: Always back up your PST file before repairing.

Method 2: Create a New Outlook Profile

Sometimes the issue is with the Outlook profile, not the PST file itself.

Steps:
  • Open Control Panel → Mail.
  • Click Show Profiles.
  • Click Add and create a new profile.
  • Set the new profile as default.
  • Open Outlook and attach your PST file again.
Method 3: Reduce PST File Size

Large PST files are more prone to corruption.

Steps:
  • Delete unnecessary emails and empty Deleted Items.
  • Archive old emails.
  • Compact the PST file from Outlook settings.
