Can I change the old email I have linked to my accounts?

Thank you for your swift response!

However, to link my old email address to my hotmail account is not possible as i can only link other hotmail email addresses to my hotmail account.

I tried to recover my old email address and was informed by the email address provider that it was not only deactivated but also terminated and not recoverable as i havent used it in 10+ years.

Is there any other way to help change my old xbox live email address? Perhaps microsoft could change it manually? Given that i can verify that it is my account via Identification card, phone number or facebook as i use the same email address there as i do on my xboxlive account.

You cannot transfer data from one account to another. You can change the primary email associated with the accounts though. Which may be helpful depending on what you're trying to do.

The link explaining how to change the primary email address is here

It might??

I want my xbox live account i have (with its email address) not linked to the current profile... but instead link it to the profile that i have my new achievements on.

i dont care aboht the old achievements.

Then, as an alternative, can I change the email that is linked to the information? Or somehow link two mails to the account?

You can
change the email associated to that gamertag, but you can never delete the old email or all information is gonna be deleted. This is know as "alias" this means that you create another alias (email address) to the same Microsoft Account.

Sorry to hear it. Can you please try changing the old email address using the steps at the link below.

Thank you.

When I use the link to billing, it sends a code to an old email address. I changed it in my account on the 16th. I've actually had this current email for two years, but I've been too lazy to change it until recently. When I select the link for 'not using
this email address' it takes me to the account page and reflects the changes I made on the 16th. I hit 'save' and tried again, but it's still sending the email to my old address.
