Hello,
You may try contacting an online account support via the method outlined in How to contact Microsoft Support if I have an issue with my Microsoft - Microsoft Community
Keep in mind that the Microsoft account recovery process is automated, so neither Community users nor Microsoft moderators here in the Community will be able to help with the process. We recommend checking out the following resources for help regaining access to your account:
· I can't sign in to my Microsoft account - Microsoft Support
· Help with the Microsoft account recovery form - Microsoft Support
· How to recover a hacked or compromised Microsoft account - Microsoft Support
If you're having other Microsoft account sign-in issues, use our sign-in helper tool.
I hope this information helps.
Best regards,
Karlie Weng
