FWIW - you can usually connect through a web app to the comany's email server, but it requires a VPN authrentication, or some other passcode to verify it's you.

however, on a PDA, or a smartphone device, the device needs to connect through Outlook, going to the company's mobile.companynamehere.com domain.
and you will NOT be able to connect, until the company sets up rules and a certificate for you on the exchange server side. then when you synchronize for the first time using your PDA, exchange will update your PDA with that certificate..

problem is, until the company does this, you are out of luck. just keep trying to reach the IT department - they should be giving you an answer one way or another !

I will tell you this much - I am a new PDA user, and being able to synch with so many different email accounts, all through mobile outlook (my company email included) is just about the most amazing thing. i can't imagine being without it now. .
