Event from Exchange Sever

["Samuel"]

Hello,

 I've heard of the possibility to make script fired by Exchange events 
(EventSink). The problem is that all the test I made on this doesn't work. I 
read a lot of articles on microsoft and MSDN site and I even do a step by 
step article found on MSDN but all of that doesn't work.

I thought so to try another way and would like to know if it's possible to 
fired a script by an Exchange timer? I explain. Instead of an event, the 
Exchange server will execute the script all five minutes for exemple.

Is it possible?

if not, can I have some help to create Eventsink?

I try these articles :
