About Using Messages
Users, such as sales representatives and call center agents, can use messages to communicate with others who also use Siebel Business Applications. They can create messages, view and sort messages, and associate activities and other items with messages. Using messages allows users to maintain a history of the communication associated with a contact, account, opportunity, or information request.
NOTE: The Messages functionality is unrelated to the message broadcasting and alerts. For more information, see Message Broadcasting and Alerts.
