The following elements work together to provide server-side event handling and processing using scripting and are depicted in the illustration that follows:
The Microsoft Exchange Event Service A Microsoft® Windows NT® service that runs on the computer running Microsoft Exchange Server. Using Microsoft Outlook, you configure this service to monitor events that occur in folders you specify.
Folders The folders upon which event scripting works can be Microsoft Exchange private folders (mailboxes) or public folders.
Microsoft Exchange Scripting Agent An engine that interprets user-defined scripts. This element is a Component Object Model (COM)/Automation component that exposes theIExchangeEventHandler interface.
User-created scripts These scripts, which use the CDO 1.21 COM component and its provided objects and interfaces, constitute the actual program that works on folders. Scripts are stored as properties of hidden messages in the folder and as such, travel with the public folder application. These messages are visible only through the Agents interface or through a utility such as Mdbvu32.exe, and are hidden to Microsoft Exchange clients such as Microsoft Outlook.
Other related elements—not seen in the diagram—are these:
Microsoft Exchange Administrator program A graphical interface used for configuring and maintaining the sites and servers of an organization, for creating and configuring public folders, and for granting permissions to users—such as for writing and enabling scripts.
Microsoft Outlook Using Microsoft Outlook 97 Version 8.03 or later, you can create agents that respond to events in folders.
