When you realize that, your Outlook data file (.pst or .ost) file has been corrupted or running very slow, you may want to scan your PST for errors. The 'Microsoft Outlook Inbox Repair Tool' i.e. the SCANPST.EXE file helps you to easily diagnose the errors and fix them.


To get started with the tool, first you need to close Outlook and wait for few moments until the application completely exits. You can check the System Tray and make sure that the Outlook icon has been disappeared.


Now go to 'Start' and search for 'scanpst'. The file is generally available in the following path:

  • For Outlook 2007 - '%ProgramFiles%\Microsoft Office\Office12'
  • For Outlook 2010 - '%ProgramFiles%\Microsoft Office\Office14'
  • For Outlook 2013 - '%ProgramFiles%\Microsoft Office\Office15'
  • For Outlook 2016 - '%ProgramFiles%\Microsoft Office\root\Office16'

Once you open the SCANPST.EXE file, the following Window will launch where you need to enter the name of the data file that you want to scan. By default, it automatically points to the default PST that you have configured in Outlook. In case you want to change it, click 'Browse...' to select the correct data file.


The Inbox Repair tool doesn't connect or analyze any data stored in an Exchange mailbox. If you're using a Microsoft Exchange account and your offline Outlook Data File (.ost) has been damaged, you can safely delete the file. Outlook will recreate it the next time the application opens.
