Why is Outlook on my Mac suddenly crashing consistently?

I have been trying to open Outlook on my MacBook Pro all day, and it has consistently crashed. I was just using Outlook last night and had not made any changes to apps or settings since trying to open Outlook this morning. MacBook is running Sonoma 14.3.1. Never any issues until now. Consistent error messages....even after uninstalling and re-installing...per Microsoft support which was not very helpful.

Below is the most recent message I received (minus hundreds of lines due to character limits).

    It seems MS could escalate this issue and then issue a fix. Paying users shouldn't have to go through this rigamarole to get functionality that is part of, no IS, the core product. I'm still using Legacy mode to avoid Outlook crashing. So disappointing.

    I had the same issue today (April 4). What worked for me was:

    1. Create new profile, set as default and start Outlook.
    2. Very quickly switch to Legacy Mode.
    3. Go back to profiles and set my original profile as default.
    4. Start again in Legacy Mode.
    5. Go to Help > Clear Application Data and clear Experimental Features.
    6. Switch off Legacy Mode

    For now at least that worked...

    The only thing that works for me is to delete those two folders/files using Terminal:

    sudo rm -rf "/Volumes/macOS/Users/$(whoami)/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles/Main Profile"

    sudo rm -rf "/Users/$(whoami)/Library/Group Containers/UBF8T346G9.Office/Library/Preferences/UBF8T346G9.Office.plist"
