Outlook Inbox Repair Tool

The Inbox Repair Tool can be started with scanpst.exe. The location of this file is different for almost every version of Outlook and it sometimes also depends on which language of Outlook you have installed and even if you have it installed on a 32-bit version of Windows or 64-bit version of Windows.

You can use OutlookTools (free) to locate it for you. Below you’ll find an overview of the default locations of scanpst.exe throughout the versions of Outlook.

Outlook 2007
32-bit Windows; C:\Program Files\Microsoft Office\Office12
