Hello DarkSpawn569,

Thanks for posting on the Xbox forums. We understand that you are interested in recovering an old Microsoft account that you used to use on Xbox 360. It's great that you remember the email address to your account. The first step to recovering an account
is knowing the email address that is used for the account. You can change the email address that is used to log in to the account after you recover your password. We have a support article that explains

how to recover your password. Be sure to let us know the results DarkSpawn569!

If you dont remember the email that was used for the account then there will be no option to get the account back. Try this soloution: https://support.xbox.com/en-US/my-account/microsoft-account/forgot-microsoft-account-solution or you could try to contact
the support and get an call back from them. Hope that helps.

I doubt they can with serial numbers. They would usually ask for your answers to the verification questions you added when you created the account.
