Problem with ICSDemo, Sample of SDK 5.5

Hi...
I want to implement ICS in my service which is communicating with MS
Exchange Server. I found a very helping demo (ICSDemo) from Exchange Server
5.5 SDK. But i cant
understand the actual functionality of this demo.

I beleiver that it gives me the hierachical changes. But even if i create a
new meeting/appointment in any public folder, and on click of "Synchronize"
button, its not telling me that a new meeting has been added.

In my poor understanding, when a new change will be found in Exchange
Server, this demo should notify me that change accordingly. But currently, it
says nothing...?? Can any of the Gurus there can sort this problem??
