Hi 21Redmoon,

You will need to use the Compromised Account Solution support page and follow the steps as requested.

Hope this helps

Hi There,

I don’t know what else to do, Ive asked for help many times and it all leads to the same ending. Asking for email or password or phone number… Which yes I know it makes sense to get your account back but I currently don’t have any information on my xbox account. Gamer tag to that account is “Epiluction” very old Xbox 360 account, I lost it during my transition from Xbox 360 to Xbox One when it came out recently back in whatever year it came out but that’s not the point , the point is when I tried to add my xbox 360 account to the Xbox One , it created a whole new account, and ever since that day I lost it because I have no idea about the email, password, nor phone number associated to that account because it was created from a family member of mine and that person is currently gone. So I just wanna know if there’s any other way to login into an Xbox account/ Microsoft account, because my gamers out there, you know the feeling of the good old days. I was at least 9-10 years old playing Halo Reach, BO2, MW2 etc. all the game captures I have, all the achievements I was awarded, the memories that were forgotten, I need this account back please, if anyone could help me. Or Microsoft please help me , anyone??? Currently 19, still fighting for this account because it’s just the memories that I need to be reunited with. To heal. Please help. Once again, gamer tag is “Epiluction”. Please , anything or any help is great . I appreciate anything.

How do they know that you're the owner of the account? you could be anybody, as Nursemorph said, without a valid piece of information like an email address, password etc there is nothing they can do.
