Hi there! My name is Darhyl and I’d be more than happy to help you with your query.

I'm sorry you are experiencing this with your Microsoft account. No worries, let me help you sort this out.

It's important to note that this is a public user-to-user community forum, and none of us here work for Microsoft.

If I may ask, did you remove the primary email address of your Microsoft account prior to this error?

According to a fellow independent advisor, Diane Poremsky [ M365 MVP ]: You will need to contact Microsoft to have the address restored to the Xbox account.

Best Regards,

I didn't receive any mail from Microsoft regarding my Microsoft account deletion.

I tried filling the recovery form but it said that "The Microsoft account you've entered does not exist"What am i suppose to do i don't wanna lose my microsoft account

Hi Gagan, based on all the information on the post.
I'm afraid to say that it seems your account has been compromised and the hacker managed to change the email address associated with this account.

You can try to recover it by following the suggestions provided in the Microsoft interactive guide below:

Hello Gagan, may I know if you received a security notification from Microsoft regarding an account information change?

If that's not your case, I'm afraid to say that if the recovery form doesn't work, it is not possible to recover the account.
