I notice that members at the HTC Wizard Web have a lot of questions about Push E-mail. How does it work? How is it different from regular synchronisation and the SMS triggered AUTD v2 over the air synchronisation?

On msexchange.org I found an article titled Exchange 2003 Mobile Messaging Part 1 - A look at the Microsoft DirectPush technology that explains just about everything about how DirectPush works. They start with explaining where we are coming from:



Quote:
Prior to Exchange 2003 SP2, you had two choices for synchronizing a mobile device with a mailbox; you could manually configure ActiveSync on the mobile device to issue synchronization on a scheduled basis, or you could make use of the Always-up-to-date (AUTD) technology. The problem with scheduled synchronizations is that you cannot schedule them for intervals less than five minutes, which means you will not always have the latest information on your device. Another problem is that you (depending on your mobile operator) will be charged for each established session, as new data will travel over the wire, each time a new session is established.

AUTD makes it possible to keep your device up to date by generating an Exchange store event in the user’s mailbox. When the store event detects a change in the mailbox, it triggers a Short Message Service (SMS) control message, which is then sent to the user’s mobile device. When the device receives the SMS message it initiates synchronization with the Exchange server. The idea behind the AUTD technology is good, but unfortunately it doesn’t work very well in reality, at least not in Europe where very few mobile operators supports AUTD. Microsoft IT became aware of this problem, when they deployed Exchange 2003 based mobile messaging in their own organization – an organization spread all over the world.

Then they continue with a four page long explanation of everything you ever wanted to know about the Microsoft DirectPush technology.

Enjoy!
