How can I find the xbox one account that is currently used by Xbox live

Hello!

Hope you are well. I'll be glad to assist you.

I'm sorry you're experiencing these issues.

If you’ve used different email addresses and can’t remember which one is linked to your Xbox account, try signing in with each of them at this website:

https://www.xbox.com/play/user

Once signed in, if you see your games or gamertag appear, that’s the account currently linked to Xbox Live.

I hope the information has been clear, I will be attentive to any questions you may have.

Best Regards.

Once an account is created you can't delete it.

However you can change the email associated with an account, which will then free the old one up for a new account.

Head to this page
support.xbox.com/.../manage-live-id and pick the Switch Your GamerTag to a Different Windows Live ID option to find out how to do it.

-

In short create a new hotmail account and use that to replace your current email address. That will free that one up and you can then use it to create a new account.

You will have to promote your local account to a Live one. This will require a new email address that is not already linked to a Live account.

If you want to use the one that is tied to your current Live account, then you will need to change that one to a different email address which will free the old one up to be used when promoting your local Profile. Information on how to do that can be found
here

unfortunately you cannot combine accounts (if that's what you're asking about). you can attempt to delete that account and then change the gamertag on the account you currently use, but it is not guaranteed that you will be able to get it. you can find
out how to change your gamertag here:

Nothing can be transferred between accounts. But you can find how to change your email here -
