Sorry maybe I should clarify - I do understand that I use Active Synch to synch my desktop outlook through the USB connection to my PDA but how does it work on my internal wireless network? Do I configure Pocket Outlook to point to exchange server after I authenticate on the wifi LAN? The PDA doesn't go over the wiFi LAN to find my desktop PC to connect to... does it? Is there a difference between wireless LAN and just WiFi cards and does the Ipaq do both?
