Managing personal Outlook.com account settings, security, and privacy
If you no longer have access to the recovery information, unfortunately the account recovery form is the only available option to try to regain access. The process is automated, so Microsoft Support cannot manually bypass the verification or recover the account for you.
Try to provide as much information as possible, even if you are unsure about some answers. If the attempt is unsuccessful, you can try the form again.
Also, please keep in mind that this is a public user-to-user forum. No participant here has access to your account or personal information.
