Xbox live account email address

if your email address is a Microsoft email (@hotmail, @live, @outlook) then you wont be able to remove your account from the Xbox account.

removing Microsoft email accounts from Xbox accounts permanently deletes the email account and you will no longer be able to access it

all you can do is add an alias email address then promote that to be the main email address.

Unfortunately there is no way to merge to accounts. But you can add your new email address to your existing live account.

Easiest way is to add your new email address to the Microsoft account where your gamertag is bounded to. Then set this email address as primary address there. Before you can set it as primary email address you have to delete your new live account of course.
You will then be able to log in to your pc and to your Xbox with the new primary email address.

You can do this at: http://account.live.com

You will need to change the email address on the "dummy" account to something else, so that is becomes free to use with another account. Then you will be cable to change the email address on your main gamertag using this
email address.

To change the email address, go on your Xbox, select Account Management and then Windows LIVE ID.

As additional information

there can only be one xbox live account connected to an email address, so to create a different xbox live account you will need to use a different email address.

Also be aware that a gold subscription is per account and is needed for online game play.

I know the email address I used to create the XBOX Live account - [mod removed]. I tried logging into XBOX Live with this email address without success. Is that the information need?
