No Teams Allowed

So yesterday I was searching Halo all fine and well. I invite a friend to join, and then all of a sudden I can’t search. I forget the exact message, but it was some network error type message. I quit the game, restarted it and same issue. I couldn’t even search alone. I turned off the Xbox for the day.

Today I start searching alone all fine and well again. I play a few games and decide I want to start searching with some friends. I invite them and go to search; I get the exact same issue. Quit the game and can’t search alone either.

Hey OP, there was a large Xbox Live outage yesterday which affected a lot of people. Looks like there are still some latent issues today, you can use this topic to stay up to date:
