2 accounts same email.

A new account has been created, meaning the email was no longer associated with your account when you tried to sign in. It's likely the account was compromised and your email was removed from it; in these cases I'm afraid it's not possible to recover an account. I apologise for any inconvenience caused by this

For future reference, see the following page for tips on keeping your account safe and secure: https://support.microsoft.com/account-billing/628538c2-7006-33bb-5ef4-c917657362b9

Thanks,

Hi Ferenc. My name is Kyle and I'm an independent advisor.

I understand how frustrating it must be that you are experiencing this. Please sign into your account from this page: https://account.microsoft.com/

Does the account you signed into show any of your purchases or subscriptions?

Thanks,
Kyle

No problem Ferenc. Please reach back if you have further questions.

Thanks,
Kyle

Hi! I'm Rostom, an Independent Advisor. I will be glad to help you here.

Please be informed that there's no way we can have two or more accounts using a single email address. Your other account must have been linked to a different email address.

Please check your email history or other devices where your original account might still be signed in by checking your Xbox profile on https://account.xbox.com/Profile.

Check the link below for more tips in getting back your correct email.

I see... as we do not have insight into accounts I advise contacting a Microsoft Support agent so this can be looked into further. See this link: https://support.microsoft.com/contactus

Thanks,
Kyle
