This is not going to work because I forgot my email address

Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello Sample, since you don't remember the email from the account, you should try to remember what the account is or follow the steps below to see if you can find the email you used for the account.

Xbox Support can’t provide this information, even if you know your Gamertag.

Recover using your Alternate phone number or email address:

4. Choose Forgot my username from there you will be ask for alternate email or phone number that you use with that account, if you enter it correctly then you will be able to see the right email for your account.

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

Thanks for the help

I tried all this but it still doesn't show up.

Recently I reseted my xbox, and when I tried to connect to my account with my email, it asked me to put a new username. I think I can't find my old account. I only remember for sure the username.

Maybe that's the problem
