I can't remember my Microsoft account that is associated with my gamer tag

I am not sure how it happened. I already had a Microsoft account. When I got my xbox I created an account and got a gamer tag while setting up my xbox. I signed up for xbox live from my xbox using my existing gamer tag and Microsoft account. I then went
to xbox live and signed in using my Miicrosoft account, and for some reason when I did this a new gamer tag was created and associate to my Microsoft account. So, now when I log into xbox live I see one gamer tag. But on my xbox I have a different gamer
tag.

DarkRaider777,

There is no way to delete a gamer tag. You can pay to have it changed, but deleting the Microsoft Account will not delete the associated gamer tag and will only make that gamer tag inaccessible since there will no longer be a supporting Microsoft account.

I logged on to my live account and it's does not have my gamer tag RAPIDxxKAOStagxx27 instead there's some gamer that's not associated with mtg account. Why is this?

No we can't log into the email that has the account gamertag associated with it. Nor can we log into the Microsoft account....

The only place the gamer tag is logged in is the Xbox.

So then saying log in add a new alias doesn't work cause we can't get a code.

They want us to remember subject lines of emails from an outlook account we haven't used in years

How can I get my old gamer tag....I can't remember the email
