Enabling a Folder for Routing

The routing engine is implemented as a custom event handler running on the Microsoft Exchange Server 5.5 Event Service. In order to link the engine to the events firing in a given folder, an instance of this event handler (an Agent) must be created in the folder. This is also known as creating a binding between an event handler and a folder. This action creates a hidden binding message in the folder that describes the event handler, the events to act on, and any handler-specific properties. In the case of the routing engine, the handler-specific properties include the default map for the folder, and the set of VBScript actions (see Script Actions) to be used by maps in this folder.
