I've used Remote Desktop on Mac regularly to connect to a domain-joined Win11 machine in my house. Just recently, it's stopped working. This happened on two macs, and it had the same suspicious start...
Let me get this straight... You have 6 people tell you about a problem. Nobody from Microsoft responds for almost 2 years after the issue is opened. When Microsoft does, you advice is: Follow our "troubleshooting options in the documentation"... which I find a bit insulting as I'm certainly going to do that before taking the time to draft a post to ask for help.
Really, it's no wonder so many people don't trust Microsoft. You're not supporting your users.
