How to turn off Microsoft Exchange Notification?

Hi,

I'm constantly being asked for the Exchange password for my work account on all my Apple devices ("Exchange password required").

I have the account installed in Outlook, but I've turned off notifications for Outlook (as well as for all other Microsoft apps). Additionally, the account is activated in the Mac system, but only for Calendar. I've also tested turning off notifications for Mail and Calendar, which made no difference.

Nevertheless, the intrusive banner with the Microsoft Exchange symbol and alert sound appears, and if I dismiss it, it comes back after about a minute. I don't get any options to disable or mute it; I can only "Continue" or, with a right-click, go to my notification settings, but there is no relevant app that is still active.

The problem occurs both on the iMac (2017, Ventura), as well as on the MacBook Pro (2015, Mojave) and the MacBook Air M3 (Tahoe).

Why don't I just enter the password? Because I would have to do it after every sleep mode and on every device, including two-factor authentication, but I don't need my work appointments constantly freshly synced on the computer.

Why don't I just leave it? I can on the iMac, it's only sometimes annoying because I only occasionally need to do something in the top right corner, but on the laptops, it takes up a considerable part of the screen.

Thank you in advance for your help.
