การจัดการการตั้งค่าบัญชี Outlook.com ส่วนบุคคล ความปลอดภัย และความเป็นส่วนตัว
Hey there! Nice to meet you!
If you do not have any linked verification methods for a password reset, I'm afraid the only way to recover the account is through the account recovery web form: https://account.live.com/acsr
Important: If you have an active 2FA, ACSR will inform you that your recovery request will be ignored. If you only receive a message that the recovery request is either successful or indicates insufficient information, this means that 2FA is disabled.
You'll need to keep trying until you're verified by Microsoft, and you can do this up to 2 times every 24 hours.
Please be advised that Microsoft Support will not be able to grant you access to your account.
In case you are unable to recover the account in order to manually close/delete it, it would be best to wait for the account to be deleted due to inactivity since you mentioned that you haven't signed in to it for many years.
As stated by Microsoft, accounts that have not been signed in or have been locked for more than 2 years will be deleted due to inactivity, and they can no longer be recovered: https://support.microsoft.com/topic/microsoft-account-activity-policy-7c0a9fa7-0982-b7c6-fd72-df852b63699f
Lastly, you may block the security notification emails in your Outlook mailbox by right-clicking the email in your inbox, selecting "Block," and then "Block Sender."
Thank you for your understanding.
Best regards,
Darhyl
