Microsoft Outlook recommends using its built-in Inbox Repair tool, also known as ScanPST.exe, to repair damaged or corrupt Personal Folder (.pst) files. The tool checks the data integrity errors in the Outlook PST file. If inconsistencies or errors are found in the scanned PST file, ScanPST.exe tries to fix the errors and inconsistencies by removing the bad items from the PST file. This helps you get back an error-free PST Outlook data file. However, to use the tool, you need to find its location. Below, we will explain how to locate ScanPST.exe on your system.
