Dear plankPG,
Welcome to Microsoft Community.
We understand the importance of getting this account back and we apologize for any inconvenience this may have caused you.
Please know that the Microsoft account is managed by a full automated server, and no one has manual access to it. All of your security information in the account is managed, stored on the Cloud Server, and managed by the automated server.
If access to the email and phone number associated with your account is no longer available, you will not be able to reset your password through the normal process. However, you can try to recover your account by filling out the account recovery form.
The Microsoft account recovery form is meant to be the last option for you to get back into your account. This form is designed to help users who cannot reset their password or access their account due to a forgotten password, lost phone, or other reasons. The recovery form allows you to prove that you are the owner of your account. Be sure to provide accurate information that you can.
You can fill out the form: Recover your account (live.com)
Thank you for your time and understanding.
Best Regards,
Peter.Y-MSFT | Microsoft Community Support Specialist
