How to retrieve an email adress linked to an account

Hi,

So basically i remember my old's account username and password but since i didn't log in like 1 years or 2 years on this acc, i have to enter a code sent to the mailbox linked to that acc. But i have dozens of mailboxes and i can't find the email adress and im stuck.
