Managing personal Outlook.com account settings, security, and privacy
Hi,
Unfortunately, the only way to regain access to your Microsoft account is by submitting the Account Recovery Form. Microsoft Support will also direct you to this process, as they do not have the ability to access or change your account information.
Microsoft takes account security seriously, which is why the recovery process is automated and cannot be manually changed by MS support. To improve your chances of success, please provide as much accurate information as possible to verify that you are the rightful owner of the account. The more details you can provide, the better your chances of passing the verification process. Please note that if your primary email address, phone number, aliases, and security information have been deleted or replaced, unfortunately, there is no way to recover your account. This is a difficult situation, but please understand that the recovery process exists to protect your account and its contents.
If your recovery request was denied or unsuccessful, please click the link below for more information.

If you have not received an email regarding your recovery request, please check your spam, junk, and other email folders. Also, make sure to check the same email address you provided in the recovery form, as that is where Microsoft will send its response.
It may not be the outcome or solution you were hoping for, but I hope this helps address your concern.
Stay Safe!
