All about ScanPST (and ScanOST) tool


scanpst-iconQ. What is ScanPST.exe (and ScanOST.exe)?

A. ScanPST.exe is a tool to repair corrupted Outlook data files. It is useful to run when:

  • Outlook is slow to load and open files
  • Can't drag and drop emails or folders
  • Can't open email

It works equally good on repairing PST and OST (exchange data file).

For seasoned admins, the main question is:

Where is ScanPST.exe (ScanOST.exe) located?

Outlook 2010 x32

Windows x32 C:\Program Files\Microsoft Office\Office14
Windows x64 C:\Program Files (x86)\Microsoft Office\Office14

Outlook 2010 x64

Windows x64 C:\Program Files\Microsoft Office\Office14

Outlook 2013 x32

Windows x32 C:\Program Files\Microsoft Office\Office15
Windows x64 C:\Program Files (x86)\Microsoft Office\Office15

Outlook 2013 x64

Windows x64 C:\Program Files\Microsoft Office\Office15

Starting with MS Office 2013, ScanOST has been dropped and it's functionality has been replaced with ScanPST.
