The chat’s archives stores each chat session, where you can view it at a later time.
The system archives a chat session once all chat members leave the room or after more than 20 minutes of inactivity. Chats appear in the Chat Sessions list.
Note For a general chat, you must be in the org unit where you created the general chat to see its session archives.
Note For personal chats, only the chat’s creator can delete sessions from the archives.
