Managing personal Outlook.com account settings, security, and privacy
I’m sorry you’re going through this issue with your account.

I understand this may not be the outcome you were hoping for, and I truly appreciate your patience.
The best next step is to complete the form here, is not the same as the recovery form: https://aka.ms/recovermyaccount
Once you submit it, your request will be reviewed by the team that handles account recovery situations like this. They will reach out to you by email with the next steps or let you know if they need any additional information to continue helping you.
