Outlook for Mac keeps crashing - what's the fix please?

Anonymous

I am using Outlook (latest version) on a Macbook Air running Monterey (latest version - 12.7.1).
ie all software is up to date.  

Outlook keeps unexpectedly closing/crashing, for no apparent reason. --

-- Below are two examples of the first part of the kind of error message it gives me, from two Microsoft Error Reports.   (It is too many characters to be able to paste one errror message in full!). They then go on to list various Threads and Thread States?

Please could someone help? I'm afraid I am not at all technical! Many thanks.   :)

Hello AndreaM1971,

Thank you for posting to Microsoft Community.

I understand that you have an issue where the Outlook app for Mac is crashing on startup. My apologies for the inconvenience that this is causing you.

Based on the error description, could you kindly try setting up your account in a new Outlook profile and see if issue persists: For reference: Manage profiles or identities in Outlook for Mac - Microsoft Support (Do not delete the current profile as yet to prevent any data loss).

If the issue persists, you may have to uninstall and re-install the outlook app. Please refer to steps below. (Please backup the outlook folders before moving to trash).

In Finder >go to the Applications folder
Drag/Move the Microsoft Outlook app to the trash.
Restart your Mac.
Run this installer to reinstall Microsoft Outlook Install package.

Looking forward to your response.

Sincerely,

Ashraf.

On the Mac, run terminal and enter this command to disable new Outlook on Mac.

defaults write com.microsoft.Outlook EnableNewOutlook -int 0

Open Outlook and it will be the old version which works fine.

Hello Ashraf,

I am running Mac OS Sonoma and Outlook keeps crashing.

It barely starts up and closes.

It shows the same Error report.

I tried all of your suggestions but it did not help.

Do you have a solution for it ?

Thanks

Carlos

Same here..
This was often the case in the past. Then it was better.

With the new version it's really bad now.

Outlook crashes every few minutes.. working is hardly possible anymore
