Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello Greece, the change of "Alias" can only be made by the account owner, it is made by the link below.

But if you're referring to your account being compromised, you should try to recover it from the link below.

I tried this exact method, however when attempting to change the primary alias, no matter how many times I click "make primary" it would not change the primary alias. It is now saying I've changed my primary alias too many times this week even though it
hasn't changed once.

Hi there Cade. It sounds like you may want to try
changing your Microsoft account email.

Additionally, if you're referring to
changing your Microsoft account alias, those steps can help.

Yes you can change the original email address. This process is called changing the primary alias. The primary alias is the email address that is used to sign in to the account. The article explains how to complete this process.

Hello ChloéThery,

Thank you for posting on the Xbox forums. We understand that you are interested in

changing your primary alias. If you are receiving that error message, it means the email address you want to use is already the primary alias of a Microsoft account. You must first log in to that account. If you need help

resetting the password, you can use our support article. Once you have logged in to that account, you can change the primary alias for it. After you have set up a new primary alias on that account, you can remove the email that you want from it. At that
point, you can go ahead and use that email address as the primary alias of your main account. Be sure to let us know the results!
