Managing personal Outlook.com account settings, security, and privacy
Hello
This is terrible. I am sorry it happened to you.
I would suggest that you go to https://msrc.microsoft.com/report/ scroll down, and use the Outlook Spam to report impersonation.
Because this appears to involve impersonation and possible fraud, I also recommend reporting the matter to your local law enforcement agency. They may be able to investigate further, particularly if there is evidence of financial fraud, identity theft, or other criminal activity.
