Is there a way to change the email associated with my Xbox Account?

You just promote your account on your console

Should be noted you can't change your email if it's a outlook or hotmail account

Only external emails aliases can be changed

Hi Rukia! My name is Ricardo an independent advisor ready to help you with this situation!

You can add a different email address to the account, but to completely unlink your mom's email from it, the email will need to be deleted from Microsoft, if the email it's not from Microsoft there would be no problem, but if it is, you will lose access to it

Hi there,

as far as I know you are only able to change the associated Microsoft Account connected to an Xbox Live account via the xbox 360 console.

Currently there aren't any other ways to change the associated Microsoft Account (email address) sorry
