Getting new email to gamertag!

My issue:

I've got two emails.

Email 1: The email that my Gamertag is attached to. I made the email specifically for the gamertag a long time ago.

Email 2: The email that I currently use for everything. It has a microsoft account and a gamertag that I didn't make for it due to me signing into xbox.com with it.

What I want:

I need Email 2 to be the account that my Gamertag is attached to so my phone, computer, and xbox are all on the same Email.

Can you sign in Xbox live with a different E-mail account?

yeah just create a new email address, go to xbox.com and change the email associated with your gamertag. heres the lnk for you.
My account : Gamertag and profile

 

Ran into an issue with backwards compatible games. (Please Help.)

It gives you an option to download new profile (Gamertag). It will have you enter your email address and password, and everything should be there. I changed my Gamertag last week and everything worked perfectly fine.

 

this is what your going to need to do to switch the emails on both account a 3rd account does need to be made.
