trying to get my old 360 account back after forgetting my old email but i rember the gamertag

Only way to do this would be to contact xbox support by going to support.xbox.com/contact-us and giving them the gamertag and if they can verify ownership of the account they would be able to give you the email address associated with that gamertag.

Il try that tomorrow thanks for pointing me in the right direction.

Well, I don't need to change my gamertag for my new (accidentally) created account. I just need to log back into my old xbox account.

And if I try to use my old gamertag, it says that it's already used. Trying to add a # makes it say that I need to have 12 characters or less.

My email doesn't access 2 accounts, it only accesses the new one and I can't log back into my old one.

Here's the thing, I know the e-mail address associated with the old account as well. Problem is, it was a yahoo acount which is also old and needs to be reactivated/reverified. Apparently when I was 15 i used bogus info while signing up, and so my attempts
to regain access to that account are also running into a wall
