Microsoft will not let me sign in with my Xbox outlook account or its alt email

That would be the best way to check since this message appear only when the account got hacked and the email was changed, my friend.

You can also try with different browsers on an Incognito / Inprivate tab.

Hello, Bob. Thanks for reaching out. I'm Lucas, an Independent Advisor and a Microsoft user just like you. I'll be glad to help you out.

Do you receive this error message when trying to sign in to a Microsoft website? If that's the case, maybe your account got hacked.

The only way to know for sure would be to sign off your console and try to sign in again. But if your account was really hacked and the email changed, you won't be able to sign in to the console again and would need to try to recover the account.

Let me know if you are able to remove and add your account from the console and sign in to it again.

I just signed out of the profile to the Whose playing today screen and clicked back on my profile. Everything is the same. I have tried signing in on chrome and edge.

Now the number after it is different and all of my Gamerscore and data is gone. My tag is now Doomguy666#4543 its supposed to be Doomguy666#6180

Please pick the same gamertag you were using, no issues my friend.
