Hello Dr. Cambois,
Thank you for reaching out and sharing the details of your situation. I understand how frustrating it must be to lose access to your Hotmail account especially since it’s linked to many personal services.
Microsoft blocks accounts when unusual sign-in activity is detected to protect your data. Recovery is handled through an automated process and support agents cannot manually override it for security reasons. The best option is to use the Microsoft Account Recovery Form and provide as much accurate information as possible, such as old passwords, folder names, recent email subjects and billing details if applicable. Submitting the form from a familiar device and location improves your chances. If you’ve enabled two-step verification you’ll need access to your verification method as the form cannot bypass that. If you don’t recognize the recovery options try the Sign-In Helper. You can submit the form twice per day and many users succeed after multiple attempts.
Have you tried completing the recovery form from a device and location you previously used to sign in?
I hope this answer is helpful if you have further questions feel free to reply back
Regards,
Marcelo
