Teams channels vs chats: when to use which

Channels inside a Team are for ongoing, topic-based, discoverable conversation that new joiners can scroll back through; chats are for quick one-to-one or small-group conversation that isn't meant to be a permanent record. Putting everything in chat means information gets lost and new starters can't catch up on context.

Coach's tip: if you find yourself explaining the same thing in three different chats, it probably belongs in a channel instead.
