Connect Azure RDP, "The logon attempt failed"

Since Windows 10, you need the domain is automatically set to MicrosoftAccount followed by your email address as username. MicrosoftAccount\[email protected]

Instead, the username is like UserName.com\My. This worked for me.

What worked for me was changing the RDP login screen to use a different account, and use the "local account" which is the name of the VM and the username, like so:

TheVMName\TheAdminUsername

Where TheVMName is the name of your VM, and TheAdminUserName is the admin user name you used for that machine. I was able to find/confirm the latter on the Reset Password screen under the SUPPORT + TROUBLESHOOTING section on the left.

I have no idea why, but the solution is simple (works every time, at least for me): I was copy-pasting the passwords from a KeePass, as i use this to generate and maintain the huge amount of credentials i use one way or another.

SOLUTION: instead of copy-paste, type the password

The drawback is that i have to use simpler passwords for this access
