How do i stop this person from joining my invite only party

Hi,Martin! I'm Luis, a fellow Xbox Gamer . Thanks for reaching us out here.

Blocking him and using an invite only party shuld be mor than enough. Are you sure none of your friend are inviting him in any way?

You can file a report as well and hope for the Enforcement team to find suspicious activity to get him off the platform if guilty

Ok Martin you will need to wait. The enforcement team investigates this thoroughly. A decision is usually made between 24 and 72 hrs after the report is submitted

I see, how long ago did you report him?

hi,

what I suggest you do is to get you and your friends to report and block the user. When you report someone, it'll probably take a few days in order for Microsoft to take action upon receiving the report.

Also when you report somebody and action is taken (for example suspension or ban) then you and your friends should get a message stating that action has been taken against one of the reports that was filed however keep in mind that the message does not tell you that if they banned or suspended the account or console, it'll just say that Microsoft has took action against one of the reports that you have filed.

Upon receiving the message, you won't be able to reply to it.

Keep in mind, that the last time I received a message stating that Microsoft took action against one of the reports I filed was from a couple of years ago so I am unsure if Microsoft still sends automated messages out to people who filed reports against that user. I assume they still do.

Ok, I will just wait and not play on my xbox for a few days and I will reply back when I get back. Im going ti be out of town today so I wont be able to reply for the rest of the day
