I had this exact same thing happen to me a while back. Luckily the account was one I had created just for this one user group who required I become part of their AD domain to access MS Teams. I tried getting back into the account and hit the same roadblock this guy did. I didn't care that much and just abandoned the account.

I figured it was something that Microsoft would soon fix, as it was such an obvious cluster; I'm surprised the issue still exists.

This has got to be the most Orwellian thing I've read today, and Microsoft saying this unironically is just bizarre:

“Windows openly enables applications and services on its platform, including various web browsers,” says a Microsoft spokesperson. “At the same time, Windows also offers certain end-to-end customer experiences in both Windows 10, and Windows 11, the search experience from the taskbar is one such example of an end-to-end experience that is not designed to be redirected. When we become aware of improper redirection, we issue a fix.”
