Mac Mail has stopped downloading emails from Exchange server

[Cave Man]

Yesterday, it was working fine, today it won't download emails from the Exchange server. Using current Tahoe 26.2 on Mac Studio M4. If I log onto the mail server using Safari/Outlook I see the new emails fine. If I click on the "Get Mail" icon in the menu bar, the new emails do not download and the activity message at the bottom of the left pane is "No new messages," even though there are. If I quit and relaunch Mail, it will download once, but not thereafter. I have restarted the computer and that did not solve the problem. Any suggestions as to how to get this fixed? I don't know if it's a Mail problem or an Exchange problem.

TIA!

A follow-up; our IT people say they have "noticed issues with Apple's Exchange server". I will try to completely rebuild my mail overnight to see if that resolves the problem.

Microsoft Exchange right? This started yesterday.

At our work and my wife's college - Microsoft is not sending/receiving emails - and if they are, it's severely delayed.

Microsoft seems to be aware:

Well, that probably explains it. I'll just hang on for a day or two to see if it gets resolved. Thanks much for that info!
