Monitoring Event sink # 15 - Check event registration and its item properties - Le Café Central de DeVa - Site Home

Whenever if we work with event sink, we need to check the event registration, what're the associated items, its item properties and its importance (whether it is required or not)...

Event Registration

To receive event notifications, you must register with Exchange by creating and saving event registration items.

Event Registration items

An item becomes an event registration item when you set the content class of the item to urn:content-class:storeeventreg.

Note: For more information, we can get more details from the Content Classes article.

The following table defines the event properties for an event registration item http://schemas.microsoft.com/exchange/events/ namespace:

Property	Required?	Use
Criteria Field	No	A Structured Query Language (SQL) Where clause that specifies the conditions that will cause the event to fire.
Enabled Field	No	A Boolean value that indicates if an event registration is enabled.
