Reminds me of the fact that I lost my Xbox account because they shutdown hotmail. My account is working on my Xbox but the password reset options are not supported by the OS on the Xbox. And I can’t change the email of the account from an Xbox. The support wasn’t helpful either. I read that somebody with the same issue got them to change the mail by logging in and out while on the phone. I don’t have the energy to jump through these hoops.
There's more to this story, you've forgotten your password or something. Hotmail accounts moved to outlook.com, just reset it on a PC.
