Phone number is tied to another Microsoft account

Hello, please try checking this link for more information I received a "This phone number has already been taken" message (microsoft.com).

If the issue persists, you may want to try contacting the phone number provider company.

You may receive the error "Microsoft account already exists. Enter another email or phone, or get a new Outlook email." You will see this message if the email or phone number you are trying to add is already tied to another Microsoft account. You will
need to use an alternate phone number, an alternate email or create a new one

Hi there,

Regrettably, it is not possible to re-associate a Gamertag with another Microsoft Account. You can

create an alias, but ultimately, it will still be tied to the original account.

The only solution is to create a new account for yourself, and use that, moving forward.

Best,

L

you don’t understand me, they stole my account from me and unlinked my phone number and mail and tied another mail that I don’t know, but my mail was not hacked, this mail has a receipt for buying an account from the official site

Have you tried to receive the security code via alternative means: phone number tied to account (text vs phone call)
