Outlook Crashes Shortly After Starting

I've tested the same user account with OSX 10.15.7 and Outlook 16.42 and the same issue happens. (with 16.49.20101102 the error is solved) There is no really a clear explanation for what to look for in the logs.

So for me its obvious, that Microsoft did change something in Office365 which makes the latest Version of Outlook on OSX 10.13.6 crash and becoming useless now. MICROSOFT PLEASE UNDO THIS! Thanks.

I am experiencing this same issue at work as of 5/27/2021. Multiple people started reporting this issue a few days ago. Here are some facts I have gathered. Are there any solutions?

This is happening to users on Macintosh computers only, with these specs:

• Mac OS 10.13.6
• Outlook Version 16.43.20110804

Other facts:

• It is not happening to everyone with those computer specs, only some of our users
• Users with issues have various sizes of mailboxes, anywhere from 1GB to 40GB
• Users with issues have various size inboxes, from 200 items up to 40,000 items
• Users with issues are from various departments within the company, nothing really in common
• Word, Excel, Teams, etc, all appear to be running fine
• If we setup a new computer with OS 10.15.x and the latest/newest version of outlook, the issue does not reoccur
• If we setup the user on a PC with Outlook, the issue does not reoccur

I am running the latest version of Office 2016. I tried creating a new identity, then resetting preferences. Neither helped. Outlook doesn't stay open long enough for me to click Help. Is there another way to contact the support tem?

Thanks,

Glen

Hi GlenEffertz,

Thank you for choosing Microsoft community.

Please make sure your Outlook for Mac has been updated to the latest version. See Update history for Office 2016 for Mac - Office release notes | Microsoft Docs.

If it's already the latest update, create an Outlook for Mac identity to check if it helps. See Manage profiles or identities in Outlook for Mac - Office Support (microsoft.com).

If the above methods don't help, you may consider using the Outlook Reset Preferences tool to reset all Outlook preferences to their default settings. See OutlookResetPreferences.

You may also contact the dedicated in-app support team. This team has richer experience with Outlook for Mac issues. To do so, click Help > Contact Support to communicate with the engineers there directly.

Hope it helps! If any update, welcome to share with us.

Thanks & Stay safe,
