Crashes in Safe Mode by mspst32.dll

Upon startup, Outlook directly crashes. So I tried to start it in Safe Mode but then it still crashes.

The error contains the following:

  • Problem Event Name:APPCRASH
  • Application Name:Outlook.exe
  • Fault Module Name:mspst32.dll

How can I recover from this issue?

MSPST32.DLL fileEvent Viewer events or error logs referring to mspst32.dll usually indicate a corruption in the pst-file. Scanning it with scanpst.exe will most likely fix your issue.

If that doesn’t work, verify if mspst32.dll is not located in the following location;
C:\WINDOWS\system32\mspst32.dll
If it is located there, rename it to .old or delete it.

If Outlook still doesn’t start correctly, you’ll find mspst32.dll in the same directory as scanpst.exe. Rename it to .old. Upon starting Outlook, it might go through the repair process first and recreate the mspst32.dll in the correct location for your version of Outlook.

If that fails as well, start with a new mail profile.
