It says my Microsoft account doesn't exist but when I try to create a new one it says that...

Im pretty sure its deleted because thats what other microsoft posts said about the same thing, but it still says it exists when i try to sign into my xbox account but when i try to sign into microsoft it says it doesn't exist and doesn't allow me to make another one?

That first prompt appears, but when I try to sign in to my Microsoft account, it says it doesn't exist.

No it says it doesn't exist but when I try signing in with a new email on my Xbox it says it exists or something.

That doesn’t work. It says this email already has an account. When I sign into my Xbox account with that email it comes up with another gamertag that isn’t mine that I’ve never used

Thats because the new alias (if its a Microsoft email) would have to be one that doesn't already exist because It creates a new Microsoft email when you go to add a new alias.

my account is hacked by a rambler.ru account and i think they changed my email, it says "That Microsoft account doesn't exist. Enter a different account or get a new one"
