The UDP notification work we delivered has been working correctly since its release in E2010 SP1 RU3. The underlying issue that many customers have seen with Online Mode clients has been due to view change notification issues; specifically that view change notifications are not returned in the same RPC buffer that included the move/deletion RPC operation response. This issue affected all Outlook versions operating in online mode. In the case of OL2003, this results in extra roundtrips for a client to pull notification information from the server as the original call has completed, so the RPC Client Access service has to fire a UDP notification to get the client’s attention that a change within the folder has occurred.
We have addressed this view change notification issue in E2010 SP2.
