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).

Using older versions of Outlook for Mac in business environments
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
Same boat. Problem started quite suddenly. Reinstalling program did not solve the problem. Please help - major impact on productivity.
Same issue here on Mac OSX 14.3.1 (Sonoma). Originally failed on Microsoft Outlook for Mac version 16.83.1. Updated to 16.84 (Beta) but it still fails. my only stable solution is to run in legacy mode by closing Outlook and executing the following command in terminal: "defaults write com.microsoft.Outlook EnableNewOutlook -int 0". This is a temporary workaround but I lose critical functionality in the updated Outlook format, which is reducing my productivity.
Microsoft - please issue an permanent fix.
The only thing which worked out for us are the following steps:
| To | Do this | |
|---|---|---|
| Create a new profile | Select the Create a new profile button  , and then enter a name for the new profile. |
|
| Rename a profile | Double-click the profile, and then enter a new name for the profile. | |
| Delete a profile | Select the profile that you want to remove, and then choose the Delete the selected profile button  . |
|
| Change the default profile | Highlight the profile that you want, access Set the default profile  , and choose Set as Default. Restart Outlook for this change to take effect |
Accounts added in the new Outlook for Mac will not automatically be added to Legacy Outlook, and vice versa. Before switching back, you'll have the opportunity to provide feedback on the experience and to create an in-app reminder for when additional features become available.
Your solution Victoria does not fix the issue.
Yes, I have the exact same issue. Please, Microsoft, find fix.
