Today I tried to open ost file and got a 'Outlook stopped working' box appear.
Re-booted the computer and still getting the same error.
I'm running windows 8
Any help appreciated
Solved! Go to Solution.
If Outlook stops responding at a screen that says "Processing," you can close Outlook, start it in safe mode, then close it and open it normally to fix the problem.
- Close Outlook.
- Launch Outlook in safe mode by choosing one of the following options.
In Windows 8, on the Apps menu, choose Run, type Outlook /safe, and then choose OK.
- Close Outlook, and then open it normally
