When it comes to dealing with errors (corruption) in Outlook data files, Microsoft recommends using the Inbox Repair tool (Scanpst.exe), to diagnose and repair errors in the files.

When to use the Inbox Repair tool?

Here are three common scenarios when you might try using the Inbox Repair Tool:

  • When your Outlook application does not load or open a ‘.pst’ file, and displays an error message as shown below:

Outlook-application-does-not-load-or-open-a-pst-file

  • When Outlook can’t open the set of folders, and displays an error message similar to:

Outlook-can't-open-folders

  • You receive a message that “<path to pst-file> is not an Outlook data file (.pst)”:

not-an-Outlook-data-file

How to use the Inbox Repair tool?

Let’s look at the steps you need to follow when using the Inbox Repair Tool to repair Outlook data file (.pst) file:

Step 1 – Close your Outlook application

Step 2Locate the PST file for your Outlook version (i.e. 2016) by browsing to the following path:

Office 2016 (64-bit): C:\Program Files (x86)\Microsoft Office\Office 16

Office 2016 (32-bit): C:\Program Files\Microsoft Office\Office 16

Step 3 – Inside the Office folder, search for Scanpst.exe

Note: If you cannot locate the Scanpst.exe file, select File > Account Settings > Account Settings. Click on the Data Files tab and all the Outlook data files (i.e. OST and PST files) will be listed together with the name of the account the files are associated with. But if you still cannot locate the Scanpst.exe file, try repairing Office

What if the Repair Process Fails?

If the repair process fails, try running the Inbox Repair Tool again. If the tool repeatedly fails to repair the PST file, but you are able to access the file in Outlook, you may try creating a new PST file in Outlook and copy the contents of the old PST file into the newly created file.

However, if you cannot access the Outlook data file (.pst) and it is beyond repair, the Inbox Repair Tool might not be able to repair the file. In fact, sometimes the Microsoft SCANPST utility might show an error message like:

inbox-repair-tool-repeatedly-fails-to-repair-5

Other than the inability to fix severely corrupt or damaged Outlook data file (.pst) file, the Inbox Repair Tool has several other limitations.

Limitations of Inbox Repair Tool

  • Cannot repair very large PST files
  • Cannot retrieve deleted Outlook emails
  • May fail to detect some corruption issues, as the scanpst utility only fixes the header part of the PST file, but cannot fix the damaged body section of the file
  • The probability of data loss is more when using the Inbox Repair Tool, as the recovered file may get modified after the repair process
  • You may need to run the Inbox Repair Tool several times (5 – 8 times) to fully repair your personal folder (.pst) file
