Managing personal Outlook.com account settings, security, and privacy
I wish I had better news, this forum is just a user to user forum, for security purposes no-one here has any account access, when a Microsoft account is hacked, if the hackers change the associated data like the Email... etc., then that account is usually no longer recoverable, try using the process they provide on this link to recover a hacked account, if this process is not successful, sadly, that account cannot be recovered.
