Repair broken Outlook PST files

Coming across a broken or corrupted PST file is always frustrating, so this guide will advise on how to run a repair on the PST file.

Example: Outlook can generally be running slow or may be crashing.

Resolution: The repair utility itself is stashed away in the Program Files folder. You’ll need to go to different paths depending on which version of Office you have, so I’ll outline where you need to go below:

Office 2013:

C:\Program Files\Microsoft Office\Office15

Office 2010:

C:\Program Files\Microsoft Office\Office14

Office 2007:

C:\Program Files\Microsoft Office\Office12

Office 2003 or earlier:

C:\Program Files\Common Files\System\Mapi\1033
C:\Program Files\Common Files\System\MSMAPI\1033

 Once you’re in the correct location, find SCANPST.EXE and run it normally. Click on the Browse button and select your PST file (if you’re unsure where yours is located, type “%appdata%\Microsoft\Outlook” into Windows Explorer; this is usually where they are). Click Start to run the scan. Once complete, make sure the backup option is left ticked, and click on Repair.

Once the repair is complete, it will pop up telling you so. If for whatever reason you need the old PST file back, the backup copy will be in the same directory as the repaired PST.
