Problem description: I created an email address for my boyfriend at signup.live.com and wanted to log in msn. I have already one and that works absolutely fine so I don´t understand what´s wrong.
Error code/error message: 80048821
What has been tried so far: I logged in with my own email address and it worked fine so I don´t know what else I could do. I already checked the correct writing for email address and password.
Messenger version: 8.5
Windows version: 10
