Xbox Series X doesn't recognize profile from Xbox 360 game

Hi! My name is Pam. I'm an Independent Advisor and I'll be glad to help you today.

I suggest to reset your password to less than 16 characters. That should work for backwards compatible games.

Hang on it's done it now on my 360.

So delete profile on series x for 360 then go on a 360 game on series x or xbox one let it do it itself. Go on to your Xbox 360 and then boom it's done it

your welcome

All Microsoft Xbox accounts have an Xbox 360 profile that can be downloaded to either a real Xbox 360 console or to the Xbox 360 emulated dashboard on Xbox One and Series X|S consoles. Even if you made a new account now, it would still have a 360 profile.

When you run a backwards compatible 360 game on your Series X for the first time, you will be asked to enter your email address and password. This is so the 360 profile can be downloaded. It does this because that is how the Xbox 360 does things.

Xbox series X will be the next console of the Xbox franchise. Like the jump from Xbox 360 to Xbox one. You will be able to play you're Xbox one games on the Series X and the games coming out will be out on Xbox One as Xbox series X for a limited time.
After a while they will quit making games for Xbox one and focus on Xbox Siries X
