Managing personal Outlook.com account settings, security, and privacy
Dear Raech,
Fortunately I could recover my account.
I got to this link https://support.microsoft.com/home/contact?linkquery=Hacked%20account
Once there, a person chatted with me and helped to get my account back, even when the hacker set the 2 factor authentication. Thankfully, it was possible.
I wanted thank you because I know tried to help and hope this information could help other people.
Kind regards,
Leonardo Miquel
