A Web service is a programmable entity that shares business logic over a network through a standard interface. Web services communicate through Simple Object Access Protocol (SOAP), which uses HTTP and XML to encode and transmit messages. Clients of a Web service do not need to know anything about the platform on which it is built; they only need to know how to send and receive SOAP messages. Microsoft® ASP.NET makes programming Web services and their clients relatively easy because the necessary SOAP functionality is built into the Microsoft .NET Framework.

User Information Web Service Client Components

The User Information Web service client consists of an ASP.NET application that communicates with the User Information Web service to gather contact information and free/busy status of a mailbox-enabled user over a given interval of time. The User Information Web service client searches Microsoft Active Directory® to find the computer running Microsoft Exchange Server 2003 where the mailbox resides, and then contacts the Web service on that Exchange server. The Web service then returns the contact and free/busy information to the client as an XML string.

The following topics provide more information about the User Information Web Service sample application.
