I'm a partner at a large law firm. As of now, only blackberry devices and Microsoft Outlook are allowed access to the exchange server. With a wink and a nod from the IT folks, I have a machine with Leopard installed and I'm able to access the exchange server using Microsoft Entourage. We've been told that they will not allow access to the exchange server for activesync and activesync. But that's for windows. How will exchange, activesync, and iPhone enterprise work for Mac?
