Corrupted PST Files

Microsoft provides a utility for identifying and correcting corrupted PST files called SCANPST

Here are some example problems we have seen that have been resolved by SCANPST: 

         a. Some Outlook folders are not being indexed 

         b. Outlook indexing hangs or stops at a certain percentage 

         c. Unable to add a specific PST file to X1 

         d. Unable to add any PST files to X1 

Here are the steps for running SCANPST: 

     1. Close X1 (using the File > Exit command) and Outlook -- make sure there are no X1 or Outlook tasks running in the Task Manager

     2. The Scanpst.exe file is typically located in one of the following folders:

  • disk drive:\Program Files\Common Files\System\Mapi\1033\
  • disk drive:\Program Files\Common Files\System\MSMAPI\1033
  • disk drive:\Program Files(x86)\Common Files\System\Mapi\1033\
  • disk drive:\Program Files(x86)\Common Files\System\MSMAPI\1033
  • disk drive:\Program Files\Microsoft Office\Office12
  • disk drive:\Program Files(x86)\Microsoft Office\Office12
  • disk drive:\Program Files\Microsoft Office\Office14
  • disk drive:\Program Files(x86)\Microsoft Office\Office14

     3. Double-click on Scanpst.exe 

     4. Locate and scan your PST files 

     5. If any errors are found, allow Scanpst to fix them 

Please note: We have seen cases where this utility needed to be run a few times to catch some PST corruption. You should then add back your PST files to X1 one at a time. 

Adding the same PST file through both Outlook AND X1 directly may create conflicts.
