Managing personal Outlook.com account settings, security, and privacy
Hey there, Harry Zhou
My original Microsoft account was compromised and the attacker changed the account's security information, including the email address associated with the account. I have tried Microsoft's account recovery process, but unfortunately I have been unable to recover the original account.
Unfortunately, in cases like this it is harder to get your Microsoft account back due to all of the information been changed by the hacker. Microsoft uses the information on your Microsoft account to verify ownership. If this information has been changed, files deleted and security information changed, there is less information for Microsoft to go with.
With this being said, I don't know if you have completed the Microsoft account recovery form or the Xbox account recovery form. Since you have played Minecraft and were using Xbox services, please can you complete the Xbox account recovery form here: https://aka.ms/recovermyaccount
When completing this form, please include as much information as possible, that the Xbox team can use to verify ownership and investigate what has happened. For more information on how to complete this form, please visit this link: https://support.microsoft.com/en-us/account-billing/guidance-notes-for-the-microsoft-account-recovery-form-4dd8fef1-33d2-4fbe-9352-66127ab9b50e
This form, in particular, will ask for your Xbox gamertag, and device ID (Xbox or PC), so having these ready is a good first step.
However, I will warn you that if the team is unable to retrieve your account, they will suspend it to prevent further damage. They will email you using their email address to communicate their findings. To speak with this team, please respond to their email before the case is closed. This allows you to engage in conversations with the Xbox team who oversee this form.
Hope this information helps,
Nathan
