I already have an account for XboxOne.
When Xbox app? started on Windows10, the app asked sign-in with XBox accuount,
But I don't know the mail address for the Xbox account, so I proceeded the steps.
Then another XBox account was created, and I cannot find to remove the account. How to delete the account?
I'd like to use XBox ccount I already have. How to know the mail address that is linked to the XBox account?
