Outlook for Mac suddenly will not open

Copper Contributor

On startup this morning, Outlook suddenly will not open (MacBook Air, Ventura 13.2.1, Outlook 16.71). It immediately generates a long Problem Report. 


I have Office 365.  Help?

My client had the same issue. I removed all the Microsoft application and reinstalled 16.69 version.


Please see the last thread on the below link 


@Aravind695  Thank you. Yes, total reinstall of 365 apps fixed it...for a few days. Then OneDrive would not open, so I trashed it and reinstalled it. So far so good. 


For the record: this happened long after I upgraded after Ventura.
