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.

    TODAY (31 March 13:20 CEST) ... FINALLY....Outlook is now working as usual. I was able to add my MS365 account in the LEGACY mode. Soooo nice to be back in OLD Outlook. New Outlook has so many bugs. During last week I reported 7 bugs to MS, jus because I was forced to use New Outlook.

    Hello

    I have this issue today on legacy Outlook on my MacBook Air. I reinstalled Outlook and after refreshing my emails came in except all those from 23 March. I have opened it now and the Window is saying 'INBOX: Determining changes'. Then 'all folders up to date'. But they are not. And I am not receiving any emails now.

    What is going on? It is important that I can access my emails on my Mac using Outlook. Or are MacBooks now incompatible with Outlook?

    MacOS Monterey Version 12.7.4(21H123)
