Hi, I'm John! I will help you with this.
If the email address isn’t yours but appears to be using your name, and it’s a Microsoft account, unfortunately, Microsoft can’t disclose or take action on accounts unless you're the owner.
However, if you believe it’s being used for impersonation or suspicious activity, you can report it through Microsoft’s abuse reporting steps here: https://sendersupport.olc.protection.outlook.com/pm/policies
The email address is "abuse @outlook.com" it contains space before @ because email address are blocked here.
If you’ve received emails from that account or seen it used somewhere, include any details you can when submitting the form, it helps the investigation.
You can use this form: https://www.microsoft.com/concern/scam
I really hope this information is helpful! Let me know if you have any further questions or concerns.
Regards,
John J.D.
