Microsoft Outlook won’t open add-ins problem


If we are trying to run Microsoft Outlook without success, we can check add-ins used in Outlook

Try to run Microsoft Outlook in safe mode like below:

Outlook.exe /safe


If Outlook will start in safe mode, go to Add-ins options and disable any 3rd party add-ins you see:

  • On the File tab, click the Options category
  • Click Add-ins
  • Select COM Add-ins from the Manage box, and then click Go
  • Click to clear the check box for any add-ins that you want to disable
  • Click OK, and then restart Outlook
