Managing personal Outlook.com account settings, security, and privacy
I understand that the main concern is not this account, but another Microsoft account that previously listed this address as a recovery method.
Please note that this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas only.
Because the recovery connection appears to have disappeared, please check this account’s inbox, Junk, and Deleted Items for Microsoft security notifications about an email address, phone number, alias, or security information being removed. These messages may help establish when the change occurred and whether it was authorized.
Also confirm that you are entering the exact sign-in address or an older alias for the inaccessible account. If necessary, check saved usernames and passwords in browsers or devices previously used with that account.
You can also review Help with the Microsoft account recovery form | Microsoft Support before submitting another recovery request.
If the displayed recovery options are unfamiliar, use the Microsoft Sign-in Helper.
Thank you for your understanding.
