Each chat session is stored in the chat's archives, where you can view it at a later time.
The system archives a chat session after a period of more than 20 minutes of inactivity. Chats appear in the list of session after this period.
To access a chat session:
On the Chat List page, click the Sessions icon next to a chat.
Note: For a general chat you must be in the org unit in which you created the general chat to see the session archives.
Click the link in the Start Date column.
When you are done reviewing the session, click Go Back.
