How to recover username?

Are you saying that you're not sure which email address your accounts are tied to?

It only shows 2 letters so its harder dor people to guess accounts

If you already know the addresses, why is this an issue?

Youll need to call support

https://beta.support.xbox.com/contact-us

If you are not sure what the email is that is associated with a certain gamertag you can contact xbox support by going to support.xbox.com/contact-us and requesting to talk to a support agent and give them your gamertag. They will then try and verify ownership
of the account with you and if they can verify ownership they would be able to give you the email address associated with the account.

I do know which one's they're tied to but i cannot recover those emails since i only get 2 letters to work with
