Address mail account xbox

Hi

It is not possible to merge two Xbox accounts into one single account, If the E-mail address you are using is about to be deleted I would suggest that you create an account with one of the free E-mail providers and change the E-mail address on the account
to that.

Hello!

Are they able to log into the account using the e-mail address that is on the Microsoft/Xbox account and password? If so, they would be able to log into the website account.microsoft.com with those credentials. Then go to "My Info" add a new e-mail address,
make it the primary one, and remove the old e-mail address.

This does suggest Microsoft account is associated with the wrong email. What I would do is on the Xbox with the Gamertag you believe is the right one is check the E-mail address associated with it. A Gamertag is associated with a Microsoft Account but
the E-mail address that is associated with a Microsoft Account\E-mail address can change. Hope that helps and makes sense.

to change your microsoft account you need to know your account password then go to setings>account>account security and change microsoft account. This will not work if you have outdated security info or if you have made any changes to your account info in
the last 30 days. also if you're moving to a g-mail or another accout that is not hotmail live or outlook the e-mail has to be registered at login.live.com click on sign up and register the e-mail address as a microsoft account. If you need to register your
e-mail address do not make the mistake of going to xbox .com this will automatically assign a gamertag to your e-mail address. the new e-mail address cannot have a gamertag on it. if it has you need to transfer that gt onto another e-mail address and wait
30 days for that e-mail address to become free.

Hi

If this account/E-mail was setup only used with Xbox then it should be possible to change the E-mail address on the
Microsoft Profile page however if this E-mail address is also used by your sister for any of the other services provided by Microsoft such as Skype, Onedrive, Office 365 etc then it will not
be possible to change the E-mail address for just the Xbox live account.
