Thank you for posting this in Microsoft Q&A.
If anyone is trying to take RDP to the device they will have to use the username in the format of ******@domain.com
of user account or you can also the format AzureAD******@domain.com
.
But there are some prerequisites that needs to be met to take RDP on to the device which is Azure AD joined.
- Both devices (local and remote) must be running a supported version of Windows.
- Remote device must have the Connect to and use this PC from another device using the Remote Desktop app option selected under Settings > System > Remote Desktop.
- It's recommended to select Require devices to use Network Level Authentication to connect option.
- If the user who joined the device to Microsoft Entra ID is the only one who is going to connect remotely, no other configuration is needed. To allow more users or groups to connect to the device remotely, you must add users to the Remote Desktop Users group on the remote device.
- Ensure Remote Credential Guard is turned off on the device you're using to connect to the remote device.
