After you join a group chat, you can decide whether you want to remain a member or leave the group chat. You can also remove people from a group chat.

Step 1 - Select Chat to open the chat list.

To allow members to remove each other from a group chat session, your Teams administrator needs to activate the setting. People removed from a chat session are able to view previous chat history, but cannot send new messages, react to messages, view new conversations or files shared by the group. If someone has been removed or decides to leave a group chat, their chat messages are still there in your chat history. Any changes to the chat history can be seen by them, so try to avoid editing these messages.

Instructions

Step 1 - Open any group chat of three or more people and go to the top of the chat where it tells you the number of participants.

Step 2 - Click on the number of participants.

Step 3 - Hover on the person's name you want to remove.

Step 4 - Select the X and confirm you want to remove the participant from the chat session.

An update in the chat session informs everyone that you've removed the person.
