I've done some testing, and I can say definitively that, no, UDP push notifications for Outlook 2003 have *not* been reimplemented in Exchange 2010 SP1 Beta, and I'm sorely disappointed by it. In my lab at this very moment, I have Outlook 2003 SP3 accessing a mailbox on an Exchange 2010 SP1 Beta CAS/Mailbox server in Online mode and folder updates are as sluggish as ever. A packet sniff with RPC encryption turned off confirms that Outlook 2003 makes a MAPI request to receive UDP push notifications from the SP1 Beta CAS when Outlook starts up (EcRegisterPushNotification), and the CAS rejects the request with a "MAPI_E_NO_SUPPORT" response, and, indeed, I don't see any UDP push notification packets in the sniff after this. As an experimental control, when I point the same Outlook client at an Exchange 2003 mailbox, it works as expected (push notifications in the packet trace, instant display updates on the screen).
I'm very, very cranky about this. It'd be one thing if I could back off to Exchange 2007, but of course, I can't, because Microsoft has inexplicably cut off that escape route for greenfield Exchange 2010 installs.
