Microsoft Outlook is the most widely used email client across the world. Personal Storage Table (PST) is one of the Outlook Data file formats that Outlook uses to store mailbox data, such as email folders, calendar, contacts, notes, etc. on the local machine. A PST file is also used to backup and restore Outlook data.

Sometimes, users face issues with the PST file due to various unexpected errors. For instance, a PST file may get corrupt when it becomes oversized or due to system crashes. While some issues can be easily resolved with Outlook's built-in Inbox Repair Tool called ScanPST.exe, others may seem complicated, leaving users with no clue as to how to fix them.

If ScanPST.exe fails to Repair Corrupt PST File

  • Unexpected errors in MS Outlook that ScanPST is not programmed to fix
  • Severely damaged or corrupt PST file
