The following schema defines the event properties for an event sink registration item:

Property	Required?	Use
criteria	Yes	A Where clause restriction.
enabled	No	Boolean to enable the event to be fired.
eventmethod	Yes	Defines which event(s) will cause notification.
matchscope	No	Defines the traversal of the event (deep or shallow).
priority	No	The priority of the event.
replicateeventreg	No	Defines if the event is to be replicated in a replicated folder.
scope¹	Yes	The URL that specifies the point in the store tree for which this event item is registered.
scripturl³	Yes	The name of the script if the event is a script being run by the Script Host Sink.
sinkclass	Yes	The CLSID or progID of the object containing the event handler.
sinklist	Yes	Event sink list of each event sink that has processed the event.
timerexpirytime²	No	Time to end an OnTimer event.
timerinterval²	No	Interval for OnTimer event.
timerstarttime²	No	Start time for OnTimer event.

This value is set and maintained by Exchange. The location is determined by where the registration item is saved.
Required only for OnTimer
Required only if using a script to handle the event.

For the criteria property the following rules apply:

This optional event criteria is a SQL WHERE condition.
The condition must be met for the sink to be notified of the event.
The WHERE clause criteria is limited to information in the item. It is not possible to specify conditions on data outside of this item.
The event query evaluator supports the following verbs: AND, OR, NOT, EXISTS.
Use double quotes ("") for property names and single quotes ('') for strings to be evaluated.
Custom properties must be explicitly cast to the proper type ("WHERE cast($MyNumber$ as 'i4')<>11").
