When you go to any channel in Teams, you'll either see Posts or Conversation. This is where messages in a channel take place. Everyone with access to the channel can see messages on the Posts or Conversation tab. Send a message to a channel by creating a new message or replying to one.   

Note: Some of these experiences are only available in the threads layout in Teams channels. The threads layout is available as part of the public preview program and might undergo further changes before being released publicly. To get access to this and other upcoming features, switch to Teams public preview.
