iPhone 2.0 software can now communicate directly with your Microsoft Exchange Server via Microsoft Exchange ActiveSync, giving users push email, contacts, and
calendar. Exchange ActiveSync maintains a connection between Exchange Server and iPhone so when a new email message or meeting invitation arrives, iPhone is instantly updated.

How it will work?
iPhone requests access to Exchange ActiveSync services over port 443 (HTTPS). (This is the same port used for Outlook Web Access and other secure web services, so in many deployments this port is already open and configured to allow SSL encrypted HTTPS traffic.)
ISA provides access to the Exchange Front-End, or Client Access Server. ISA is configured as a proxy, or in many cases a reverse proxy, to route traffic to the Exchange Server.
Exchange Server authenticates the incoming user via the Active Directory service.
If the user provides the proper credentials and has access to Exchange ActiveSync services, the Front-End Server establishes a
connection to the appropriate mailbox on the Back-End Server (via the Active Directory Global Catalog).
The Exchange ActiveSync connection is established. Updates/changes are pushed to iPhone over the air, and any changes made
on iPhone are reflected on the Exchange Server.
Sent mail items are routed to external recipients via SMTP. Depending on your network configuration, the external Mail Gateway
or Edge Transport Server could reside within the perimeter network or outside the firewall.
