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
