In Microsoft Teams meetings, private chat between participants is not directly supported in the same way that group chat is. However, participants can send private messages to each other outside of the meeting chat functionality. The meeting chat settings primarily control the visibility and availability of chat messages during the meeting, but they do not facilitate private chats between participants within the meeting itself.
To manage chat settings for a Teams meeting, administrators can set policies that control whether chat is enabled for all participants, only for those who are not anonymous, or turned off completely. This is done through the Teams admin center or PowerShell, but it does not specifically enable private chats among participants during the meeting.
If participants want to communicate privately, they can do so through direct messages in Teams, but this would be separate from the meeting chat functionality.
