Limitations of SCANPST/Microsoft Outlook Inbox Repair Tool

Though the SCANPST.exe or Outlook Inbox Repair tool can repair the PST file, it has certain limitations, such as:

• It cannot repair large PST files.
• The Inbox Repair tool may need to run multiple times to completely fix or fully repair the PST file.
• The ScanPST can’t repair every issue or problem with the PST file, even if the tool detects it.
• If you had recently deleted some mail items, you may not be able to recover them after repairing the PST file using ScanPST file.
• If the PST file is severely damaged or corrupt, the ScanPST may fail to repair such files.
• The ScanPST works by removing corrupt data instead of repairing it. Therefore, when it determines a specific block or table is unreadable or corrupt, it simply removes that block. As a result, corresponding Outlook items may also be removed.
• The SCANPST does not validates body-related or subject-related properties that can result in inconsistencies or loss of data or information in mail body area.
