cannot start or join a party without it disconnecting and giving me the error 0x80072EFF.

Hey, Francia your advice helped me very much as I can now speak in Xbox parties with no issues.

Did not work. Other methods i've tried are clearing cache, Clearing mac adress, Deleting profile and recovering it, Deleting recently downloaded games, Unplugging Xbox for 5 minutes and None have worked.

That's totally fine, An. If there is no other network connection that we can try to use, let's then perform a reset on your console keeping your games and apps. Don't worry because as long as you're connected to Xbox Live your saved progress, games, will not be deleted. It will remove all of your accounts but you can add all of them later on.

Press the Xbox button to open the guide.

Select Profile & system > Settings > System > Console info.

Select Reset console.

Reset and keep my games & apps.

Seems like you have performed all the necessary steps. Do you have a different network connected that we can try to use such as a mobile hotspot just to test it out?

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you in regard to your concern.

Kindly perform an extended powercycle and reset your network hardware by following the steps below to refresh the connection between your console and your router/modem:

1. Unplug the power cable from the back of the router, modem, or gateway for 5 minutes. If you have a router and a modem, unplug the power cable from both devices.

2. Press and hold the Xbox button on your console for 10 seconds or until it turns off then wait for 2 minutes before turning it on again.

3. After 5 minutes, plug the modem or gateway in first, and wait for all the lights to return to their normal state.

4. If you are using a router, plug in the router and wait for all the lights to return to their normal state.
