Lost all my account and gammer info......PLZ HELP.

You would need to contact support. As long as you can verify you are the owner of the account, they can get you the email. Then you would need to reset the password. 1-800-4my-xbox if you're in the US/Canada or

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this Travis

As you don't remember your account email, I can advise you fill the account recovery form, in that way you're going to submit a ticket with Microsoft account recovery team https://account.live.com/acsr

You can try all the emails you remember or if you had a phone number attached to the account, you can use that too.
Sadly, an account cannot be recovered with the gamertag alone.

Also, you could try alternative methods to recover your account here:
https://support.microsoft.com/en-us/account-bil...

Please note that no one here including regular Microsoft Support is not capable to send password reset links for security policies

PS: if maybe you didn’t log into the account in more than 5 years. Probably the system deleted it due to inactivity
