Using Exchange Web Services push notifications just got a lot easier, thanks to Exchange Server MVP Henning Krause. Henning has created a notification listener project on CodePlex. The listener application handles Exchange Web Services push notifications. The listener uses the WCF service model, and does not rely on IIS. Check it out, provide some feedback, and incorporate EWS push notifications into your Exchange Server client application.
