to make sure we can eliminate anything network related from the equation.

1. Press the Xbox button to open the guide.
2. Select Settings.

4. Select Network.
5. Select Network settings. Any known outages will appear in the middle of the screen.
6. On the right side of the Network settings screen, select
   Test multiplayer connection.

We hope to hear back from you soon with those results. Cheers!

Just to be sure, do you have a gold subscription?

Hi, Sorry to hear you are having an issue with Party Chat.

Here is a troubleshooting guide that may help with that

Hello YoungWu1988,

Thank you for bringing this issue to our attention. We recommend checking the
Xbox Live Gold subscription status on the account. The option to start a party is only available if the account utilized Xbox Live Gold. This can be done by purchasing the subscription, or sharing the subscription through the
home console feature. We recommend checking the
enforcement history of the account as well. A communications suspension could cause issues with party chat. Be sure to let us know the results!

Also sometimes some games won't let you start a party or send invites unless you have the game open and are past the loading screen.
