It was really easy for me to get my IT department to configure my MB (Entourage) and iphone (IMAP) to work with Exchange - I reminded them who does payroll.I even have the Remote Desktop beta up and running (so I could do payroll on vacation
).
I won't bother them for ActiveSync, though. I'm connected enough without getting email every second. I can't imagine they will let anyone else have it, either. Poor guys do spend a crazy amount of time supporting laptops and Windows Mobile devices, and Exchange administration is a PITA.
check out cord for remote desktop...it's great...

Do you vpn into the exchange server ? It drives our PC guys nuts when they see how quick and easy it is on the mac to pptp into an exchange server...
