The Web Services that are included in Microsoft Exchange Server 2007 provide an XML messaging interface for managing Exchange store items and accessing functionality on a computer that is running Exchange 2007 from client applications.
Exchange 2007 includes the following Web services:
- Exchange Web Services
- Autodiscover Service
- Unified Messaging Web Service
Exchange Web Services provides the functionality to enable client applications to communicate with the Exchange server. Exchange Web Services is deployed with the Client Access server (CAS) role. Microsoft Exchange Server 2007 clients connect to the computer that is running Exchange 2007 that has the Client Access server role installed in an Active Directory directory service site by using an HTTPS connection.
Some of the main operations that Exchange Web Services provide are:
- The Availability Service: Outlook 2007 clients can use HTTPS to connect and download free and busy data for other users through the Availability Service. Unlike previous versions of Exchange, free/busy data does not have to be stored in public folders, instead we access the target mailbox’s free/busy data directly from the calendar (via the Availability service).
- OOF: The ability to set Out-Of-Office messages is controlled by a new web service.
- OAB Distribution: Outlook can use HTTPS to locate and download the Offline Address Book (OAB) from a web distribution point.
- The Exchange Data Service operations: The Exchange Data Service operations enable the handling and organizing of items, folders, and attachments, as well as ambiguous name resolution and distribution list expansion.
- Notification and Synchronization Operations.
2. Autodiscover Service
The Autodiscover service provides a mechanism to automatically configure Exchange 2007 client applications to access the Client Access server.
It is used to set up client applications like Outlook to work with Exchange by returning configuration data that is necessary for applications to function properly without requiring users to know where to fetch the data, such as discovery of the server that hosts a user's mailbox.
3. Unified Messaging Web Service
The Unified Messaging Web Service provides an extensibility point for clients to read and change information about Unified Messaging properties. If your mailbox is enabled to use Exchange 2007 Unified Messaging, you can use Outlook 2007 to play a voice message back to a phone.
Will discuss about their configuration in detail in the coming posts :-)
