If you are trying to RDP (Remote Desktop Protocol) to a remote computer or use SMB (Small Message Block) to connect to a remote share on your home network, using your Microsoft Account, you may be frustrated that you cannot connect.
The problem is most likely that you are not specifying the domain and that gets to the question of what is the name of the domain used in a Microsoft account. The answer is pretty simple, it is MicrosoftAccount, which makes your full username: microsoftaccount\email .
In the example below you can see that the user is MicrosoftAccount\firstname.lastname@example.org
