macOS Mail.app and Outlook
The problem with mail on macOS has been dragging on for a long time. Technical support cannot advise anything, only promising that the problems will be eliminated ... someday, but this is not certain.
The crux of the problem is that by adding an Exchange account to the Mail application, Exchange works correctly from several hours to several days. Then it writes that it cannot connect to the server and that's it. Only deleting the account from the mac and re-configuring it helps.
I decided to switch to Outlook on a 365 subscription. It’s even worse, a minute after the launch, the connection is lost, in the settings the server itself changes to the wrong one. For example, the correct server is https://my.company.com, and the mail works, but spontaneously changes to https://srv-my.company.com and that's it, it doesn't connect until you fix it to the correct one and restart the application. But after launch, it also lives for about a minute and breaks down again.
Everything works fine on Windows, it works fine through the browser, it works fine on the iPhone, and even in the Mail application on iPhone it never broke.
What could be the problem?
MacBook Air (2020 or later)
