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.

Hello, this is what seems to have resolved the problem for me:

apple M3

Sonoma 14.2.1 (23C71)
1. I deleted the outlook app from the applications folder (kept it as a backup)
2. downloaded the https://www.microsoft.com/en-us/download/details.aspx?id=45492
- office installer again
1. installed only outlook
2. started outlook and it seems to work. All my folders/accounts seem to be there
Updater shows outllook update available 16.83.1 (not sure if this includes some fix, but don't have time to try it now)

But "funny" thing is that outlook shows Version 16.83 (24031120)

I have also experienced this same issue. I deleted the Outook app and reinstalled as you described.

It has not fixed the problem.

I used this approach and it worked; however could not switch back to 'New' Outlook. The toggle switch in the upper right next to the search field was gone.

I re-entered Terminal to enter defaults write com.microsoft.Outlook EnableNewOutlook -int 0, but changed the -int to 1 and restarted outlook, the toggle re-appeared. When I turned on 'new' outlook using the toggle, Outlook now crashed again within a few seconds of startup. I have three computers running Outlook (desktops at home, work and laptop for travel). My other two have this update pending, I'm going to hold off on updating until this is sorted but it's very frustrating. Please fix.

Can I join the chorus. I have exactly the same issue. Yet another major issue with this incredibly buggy program. It's almost unusable and yet MS continues to market it without fixes.

Surely someone cares enough about the customer base to address all the issues with it. Half my life is on Outlook and migrating to another program is not an option.
