Hey glad you asked, this question is somewhat rare but does come up occasionally and I decided to write about the solution here: Remote Desktop with Microsoft Account Sign-In
In a nutshell, you can fix it by doing this on the remote system you want to connect to.
- Right-click Start button, choose Run
- Type in the command below, but use your Microsoft Account email address instead of the example:
runas /u:MicrosoftAccount\username@example.com winver 3. Provide your Microsoft Account password when prompted. After you press Enter, the "WinVer" program will launch, informing you about what version of Windows you have (you can close it, you're done at this point).
Now you should be able to connect to this system without an issue (assuming, of course, the system is a "Windows 10 Pro" version).
The blog post I linked to has some more background, but this is really all there is to the trick of getting the credentials fixed.
