RM480716 - Microsoft Teams: Send messages to attendees in the meeting lobby with lobby chat

Now meeting organizers can send one-way messages to attendees in the lobby via the lobby chat. The Lobby chat is intended to optimize the lobby experience for all participants, ensuring that organizers are better equipped to run external meetings, have more control over meetings with external participants, and external attendees are well informed about the meeting upon meeting start.
