Outlook Crashes Shortly After Starting

Sorry to hear that, sir!!

We're Office 365 online support for business and have no access to server side architecture diagrams.

Sincerely & Stay safe,

I do understand and agree with you, sir!! I do hope Microsoft backend engineers could help work out a better solution for all the affected users, considering the fact that the hardware doesn't allow an update of Mac operating system!

By discussing with my team, so far the most effective method is to first update Mac OS and then update Office (the bug in a previous version gets fixed in 16.47 and later versions). See Outlook for Mac crashes unexpectedly on startup or during mail synchronization - Outlook (microsoft.com).

And would you please further try the following to see if it helps:

1. Quit Outlook for Mac.
2. Locate the following files:"~/Library/Containers/com.microsoft.Outlook/Data/Library/Preferences”
3. Move these. plist files to Trash, but do not empty Trash and delete the files.
4. Re-open Outlook, check whether the issue is resolved. If yes, you can delete the files mentioned above in Trash. Otherwise, please put the deleted files back to the old location.

Thanks & Stay safe,

Qian

It's always a good idea to check system requirements of software you want to keep using BEFORE you install an operating system upgrade. System upgrades can introduce conditions where old software no longer functions.

Thank you for your reply, sir!

I can't agree with you more. However, I checked the official articles and found that the Microsoft 365 for business products' operating system requirements for Mac OS is "One of the three most recent versions of macOS. When a new version of macOS is released, the macOS requirement becomes one of the then-current three most recent versions: the new version of macOS and the previous two versions." For your reference: Microsoft 365 and Office Resources

And this is the Mac OS history I found from Apple official site. Yours and most other users' OS happen to be out of the three most recent versions. I'm not sure if this is the only reason that Outlook crashes.

As long as I get any update, I'll let you know.

Sincerely,

Qian

Peter-Aus,

Thanks for your reply. Finally some one who gets my frustration! My issues with outlook started around the same time after I updated my phone and outlook app. Definitely not the same problem but related due to the timing of the thread I believe. I've got an alternative email app for now as all solutions on online forums have failed. My best bet right now is for an update that would fix the problem. I haven't had any decent response from Microsoft yet and it's near impossible to get technical assistance via phone. Good luck to you in getting your issue resolved.
