The details on Direct Push don't seem much like a push to me, though.
Q. What is Direct Push? A. Direct Push is a notification feature in Exchange Server 2003 Service Pack 2 that improves the user experience for users who have a Pocket PC or smartphone. This feature is available on Pocket PCs and smartphones that are running Windows Mobile 5.0 and the Messaging and Security Feature Pack (MSFP). By default, Direct Push is installed on Exchange Server 2003 SP2. Mobile devices that support Direct Push issue an HTTPS request to the Exchange server that asks Exchange Server to report any new or changed e-mail messages, calendar, contact, and task items. If changes occur within the lifespan of the HTTPS request, the Exchange server issues a response to the device that includes which folders have new or changed items. The device then issues a synchronization request to the server. After synchronization is complete, a new HTTPS request is generated to re-start the process. This ensures that the mobile device is always synchronized with the Exchange server.

If your office uses Microsoft Exchange Server, iPhone software allows you to wirelessly push company e-mail, calendar events, and contacts to iPhone over a 128-bit encrypted SSL connection. With secure push e-mail and over-the-air contacts and calendar features, users can stay up to date wherever they go. And thanks to the iPhone Multi-Touch display, they'll find it easier to perform common tasks such as accepting meeting invitations and finding contacts in the company directory or Global Address List (GAL). http://www.microsoft.com/exchange/evaluation/features/owa_mobile.mspx On Tue, Mar 31, 2009 at 1:58 PM, Jeremy Phillips <[email protected]> wrote: I guess I'm crazy too then. :) Are you sure you aren't thinking of the older version that sent an SMS to the device which initiated a pull? To my knowledge ActiveSync is most definitely push synchronization.

Activesync is a pull from the iPhone, or whatever mobile device that is doing it, Exchange ActiveSync has never been a push from the Exchange server, never.

He should be able to browse to the folders and then it'll download the messages, but it's a manual process.

While it really isn't a must do thing I have one user (also my boss) that would like his I-Phone to work with Active Sync. Exchange 2007. CAS/Hub with two mailbox servers behind it. OWA is published via ISA. Gone through all the docs I can find and I am very close. He hits it and gets all his mailbox folders, contacts and his calendar. But no mail in the folders and it keeps prompting him over and over for his password which we know is correct. What is interesting is I was also playing with RPC over https in Outlook 2007 at the same time and have the same issue. I would think it is related...what is interesting is that when outlook starts prompting us over and over for the password it is showing it is trying to authenticate to the mailbox server, using it's local domain name.
