I have one Exchange 2003 SP2 server. I have OMA active and using a separate Vdir (exchange-oma - per MS article
817379 using method #2) so I can leave "SSL channel required" checked on the \Exchange directory for OWA purposes.
I have a pilot user who has a Treo 700W with the latest firmware (1.10) from Palm and the latest Activesync software.
According to everything I have read, using the new Direct Push method (does not use SMS), the Exchange server should immediately notify the PDA that an email has arrived and the PDA should immediately retrieve it (I know this step follows
pings from the PDA etc.). Some say the new email should show up on the PDA before it gets to the Inbox in Outlook on a client PC on the LAN. Well, our pilot user gets new emails etc. only when his PDA syncs (he can set it to do so automatically every 5 minutes, or when he manually performs a send/receive). The closest solution I have seen that may deal with our issue concerns the heartbeat intervals on the server (apparently there are defaults that can be overridden
by adding about 5 registry keys and appropriate values - although I am still uncertain on what the appropriate values should be). Any suggestions on where to look to find out why notifications are not immediate and/or how to fix it are
