I've got an app that does pretty much exactly the same thing - only it Uses INDY 
instead of 
Outlook ( eugh :p ).

It's polling every five seconds, and the CPU usage only goes up to 1% when doing so 
(this is on 
a AMD-K6/500, W2K).  If you're worried about network trafic maybe only look every 
10-20 
seconds?
