I have set up BES and some Treo's so various employees can access e-mail in real time on thier PDA phones. Recently, an exec came to me with a HP IPAQ 5150 with wi-fi and want to get his e-mail in real time. We have OWA and all mobile services enabled in exchange, and work in a citrix environment. Can he get his e-mail in real time, or is active sync on his local PC the only option? Do I need to set up a VPN connection? Thanks in advance!
