how do change my xbox live email account

In fact i've received the email, but sending me on old hotmail account. How should i do to change my email address form xbox live ambassador please ?

How do I completely remove an email address from a Microsoft account that I accidentally created a long time ago, its not used for anything? I want to use that email address to sign in to my actual Xbox Live account, and then how do I change the email sign
on on the account i want to use it for?

That wasn't what I meant, what I meant is how long do I need to wait to use my primary e-mail on my primary xbox live account since I've already changed my primary email with some secondary email. Do I again need to wait for a month until I can use my primary
email to replace the email on my primary xbox live account ?

Thank you for responding. Based off the link it is connected to my current account and email information which is my parents. Changing the alias does nothing to the xbox live information it is simply to receive emails which will then change my parents email
again and mess everything up. I need to know how to completely change all the xbox live information to a separate account email and everything so it is my personal information but it seems impossible to do so without making another account, in which case is
extremely redundant and unnecessary.

If you are using a Microsoft email address (@live, @outlook, @hotmail) then changing email address will close the associated Microsoft account down and you will have no access to email or other services and products associated with it.
