Xbox Account has been replaced by a new, random one. How do I get my account back?

I want to switch the email from my older more used account, to my newer email, but I cannot seem to do so, since a Xbox account has automatically been created. How can I delete the Xbox account from my new email, so I can use my new email to replace my old Xbox account? (This whole thing started with me not being able to sign into my EA account, cause my Xbox account was signed into an older email.)

You cant. The Microsoft account IS the Xbox account. They are all one in the same.

I got an email saying that “ the security data has been changed/replaced(im hungarian i dont know which term to use here)”. And i was hoping that i would get my stuff back. And how is this different from creating a new account. I mean nothing is the same on the “new ” email(account) that i had to give to transfer the data to that.

think it has something to do with back up and account management, someone has to go through it all and replace your old GT with the new one

someone has my email and pass. for xbox . but im still signed in to my account on the commputer. how do i get my account back?

I sign in to my regular account when I sign in on the same email device, but when I log in with the same mail as XBox, a different account appears. How do I replace my new account with the account on my device?
