I am a support consultant for many customers. Getting a bunch of calls this morning (03/21/2024) about Legacy Mac version 16.8x and above not syncing.
If they switch to New Outlook, no issues. Online is also working.
Why would Legacy stop working today for some? Running Mac OS X 13.x and 14.x with same issue.
Please advise.

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.
Pfft like MS cares. They are rabid about forcing customers to adopt their inferior new version which is a shameless, featureless clone of Apple Mail. It's not a bug it's a feature!
Latest Outlook for mac Version 16.83.1 (24031813) already installed,
but not able to sync and update Inbox from outlook.office365.com since March 21, 5:11pm.
Version 16.83 (24031120) is also not syncing.
This is not accurate as I am on 16.82 (Build 24021116) and have the same issue. So you need to expand the impact!
I have clients who still have it working, and others with similar systems it is not working.
It started Wednesday at some point and has yet to be corrected.
