In Microsoft Exchange 2000 Server and Microsoft Exchange Server 2003 organizations, a public folder server is responsible for storing free/busy data. In organizations that are running Microsoft Exchange Server 2007, it is now possible to query free/busy data using a Web service. Entourage 2008, supports both a public folder server and an Exchange Web service to query free/busy data.
For more information about how free/busy data is managed in Exchange 2003, see
