Send an announcement to all breakout rooms
You may want to send announcements to give time updates, for example, or share discussion prompts.
1. Select More options at the top of the Breakout rooms pane and then select Make an announcement.
2. Enter your announcement and select Send.
Participants will receive a notification in their meeting chat to check for your announcement.
Chat in breakout rooms
Each breakout room has its own chat, and all of the chats are available in your main Teams Chat list.
Here you can chat with the members of any breakout room.
Once you’ve joined a breakout room, you can also select Chat in the room to chat with the people there.
Note: When the breakout room closes, the room chat ends and cannot be continued. However, you'll still be able to view the chat history and any shared files.
