Well, thanks... I feel better, cause I did it exactly the way you're describing. But it didn't work. I'm running Outlook on my PC, and Entourage on the Mac. Both connect to the MSE server. I looked through the account settings in Outlook, and matched up the server address on the iphone - no luck. Then I looked at my Mac Entourage setting, to see what server setting Entourage uses to connect to MSE. It's a different server "address" in Entourage, but I tried it. No luck. That's why I've ended up using our online http address to get emails. THere must be some type of security setting that not letting the iphone get through that I can't work through.
