Using Outlook for iOS for personal email and calendar management
Please note this is a public user-to-user forum, so we can't recover accounts or bypass security from here.
Recovery for personal Microsoft accounts is an automated process. Support agents can't manually verify ownership, send reset links or change account details.
Under Microsoft's account activity policy, an account not signed in to for two years is considered inactive and may be closed. If it was closed, it can't be reopened and the recovery form won't work. Since you mention it has been years, this is the first thing to consider.
If the account still exists, the only supported path is the account recovery form: https://account.live.com/acsr.
To improve your chances:
-Submit it from a device, browser and location you previously used with that account.
-Use a working contact email that is different from the account you're recovering.
-Answer as many fields as you can, even approximately, and avoid duplicate submissions.
-Note the form can't be used if two-step verification was turned on and you have no access to those methods.
