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.

  1. Close Outlook.

  2. Launch Outlook in safe mode by choosing one of the following options.

    • In Windows 10 & 11, choose Start, type Outlook.exe /safe, and press Enter.

  3. Close Outlook, and then open it normally.
