comunication ban

I have the same thing. Had a 2 week communication ban, it was lifted 2 days ago, and I still can not create parties/use voice chat etc.

What's going on?

Hey, ToneDef98! This is actually a known issue. You can see our
Enforcement sticky here and our
Xbox Live Status alert here. Please let us know if it continues once this is resolved.

did you get this fixed? im having the same issue. ive tried everything i still cant chat or message anyone. my communcation ban was lifted 10-30-17 smh thats a week ago. still no chat features or messaging anyone. Microsoft is so
bad man. one problem after another

The enforcement team doesn't monitor these forums, but I can try to point you in the right place. This could be related to reputation like you suggested, you can check your enforcement history here to see if any enforcements are in place, here:
https://enforcement.xbox.com/en-US/enforcement/showenforcementhistory . If there is none listed as active, sometimes refreshing the console could help, by holding down the
power for 30 seconds on the front of the Xbox, while its on. then trying again. If that doesnt help, follow the steps closely here https://support.xbox.com/en-US/xbox-one/xbox-live/cant-send-messages
.

i tried this and still no luck man

In that event I would suggest calling Xbox support. They may be able to confirm if any communication ban is i place and offer more steps. The number for your region is available here http://support.xbox.com/contact-us?isChatCallAvailable=false .
