Hello and welcome to our community!

We’re excited to have you here and have great conversations! I'd be happy to be of assistance.

I’m sorry to hear that your account may have been compromised. We’re here to help you regain access and secure it. Since your email address has been changed, you’ll need to use the new email address to submit a request for account recovery at this link: https://account.live.com/acsr. Once you fill out the form, someone from the Microsoft account recovery team will reach out to you via email to help you recover your compromised account. Ensure to provide the new details you have right now to hopefully recover it. Additionally, please avoid leaving any fields blank when filling out the form. If you're unsure about certain information, make your best guess instead.

If you're unsure of the new email address, unfortunately, we won’t be able to recover it directly. However, you can try retrieving your email address here: https://account.live.com/username/recover using the phone number associated with your account.

Please note that this is an online public forum, and while we help fellow gamers by sharing our knowledge and experiences, we do not have access to any accounts.

Hope the information above helps. Let me know if you need further assistance. Thanks!

Hello again, in this case you should contact Xbox Customer Service and request an ATO (Account Takeover), this is because this forum is public viewing and unfortunately as independent consultants we do not have access there is some data and procedures that Xbox Support has.

However the ATO is a similar procedure to the online form, but done by a Microsoft agent, it will need as much information as possible for you to do the procedure.
