Problems with program and account conflicts in Windows or Xbox systems are not new. It is a known fact that if applications (for example Microsoft Office) are not completely removed from the system, there is an error during reinstallation. Many users have noticed exactly the same problem with Microsoft accounts where they get the error – [email protected] is already here, another user on this device is using this Microsoft account, so you can’t add it here.
This error has been reported on Windows and Xbox consoles.
