Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I would advise you to get a temporary free email account from (e.g.) AOL or GMail or Mail.com or other free web-based email provider, and sign up for it and access it through your web browser. Then you can get the emails from Microsoft as to what to do, codes, etc.
(If you already have a GMail account or a Google account, do not sign up for GMail. It can confuse and obstruct matters if you have 2 Google or GMail accounts.)
