How do I look up an old g mail account from 5 years ago?

To look up an old Gmail account from five years ago, try recalling any usernames or recovery email addresses associated with that account. Go to the Gmail sign-in page and click on "Forgot email?" to enter any possible recovery information. If you remember the email address but can't access it, you can try the "Forgot passWord?" option to reset your passWord. If you still have trouble, consider reviewing old devices or accounts where you might have used that email.
