I understand how concerning it is to find an unfamiliar email address linked to your account, especially when the account also contains your Minecraft access.
At this point, I recommend that you review and try the steps provided in the AI generated answer on your thread. That reply typically include the most relevant checks for this scenario.
Since Minecraft is linked to your Microsoft account, the priority is to recover and secure the Microsoft account rather than troubleshoot the Xbox app. If you are still signed in on any trusted device or browser, please avoid signing out while you check whether you can review and secure the account.
Please note that this is a user-to-user support forum. Moderators and contributors cannot access account records, verify ownership, remove the unfamiliar email address, or change security information. Account recovery must be handled through the official Microsoft Sign-in Helper.
For your privacy, please do not post your full email address, Gamertag, purchase details, recovery codes, or other account verification information publicly. While my initial response may not fully resolve the issue, I truly appreciate your cooperation as we work together toward identifying the most effective solution. Thank you so much for your understanding.
