Hello,
Thank you for your response. I appreciate your time and the information you provided.
I did complete the account recovery form you linked, but unfortunately Microsoft Support responded that they were unable to locate an account associated with my email address and closed my service request.
My concern is that my Microsoft account was compromised, and I believe the attacker changed the email address and security information associated with the account. Because of that, the recovery form may not be able to locate my original account.
Is there any other recovery option available, or is there a specific Microsoft team that handles cases where a hacker has changed the account's email and security information?
Thank you again for your help.
