Solution: You can determine whether an add-in is the problem or not, simply by starting Outlook in safe mode by using the “outlook.exe/safe” command.

Solution: Generally, the Microsoft inbuilt utility ‘Scanspst.exe’ (also known as Inbox Repair Tool) can help resolve the ‘Outlook crash’ issue by diagnosing and repairing the errors found in both Personal (.PST) file and Offline Folder (.OST) file.

But, the scanpst utility has some limitations:

  • It cannot work in case of severely corrupt PST files

  • It cannot repair data files larger than 2 GB

  • While the tool can repair directory structure and headers of PST file, it cannot repair the internal structure of the data file

An alternative solution is to use a file repair software to fix Outlook crash that’s caused because of corrupt data files.
