I've recently set up work e-mail via the Exchange set up. I've noticed that the push service doesn't appear to be working properly. I've also got a BlackBerry and am looking forward to throwing it away so I can only have one phone/PDA. Basically, I would receive an e-mail in Outlook on my laptop then my BlackBerry would go off within 5-10 seconds; however, my iPhone doesn't receive the same message. It seems like it's checking the exchange server at unspecified intervals but I can't seem to wrap my mind around it. If I check my iPhone what seems like hours later, I'll see those messages delivered. Beyond that, I have to actively receive messages when I open up the Inbox of my Exchange mail account or hit the Refresh icon. It seems like going OUT, everything syncs up rather quickly (read mail on iPhone turns to read in Outlook and BB). It's just going IN is the problem. It's like the tubes are clogged. In my Settings under the Fetch New Data menu, I have Push set to ON (it was set to OFF before and the same thing happened) and Fetch is set to Every 30 Minutes. Then, under the Advanced menu, my Gmail is set to Fetch and my Exchange is set to Push. Are there any other settings I should be concerned about? Is anyone else encountering the same issues? I'm wondering if perhaps there's server setting my IT Help Desk has to change because one of my co-workers tells me he's getting his messages almost instantaneously, and we both have the same settings. I checked Apple's support page but it doesn't give much detail, so I'm hoping someone here can offer some suggestions.
