I have followed the steps from Apple, and I use a Dell Axim w/ActiveSync to retrieve my work e-mail. I am paying for the Enterprise Data Plan as well. I have setup the Exchange account correctly and have installed the cert even though it's not necessary. The iPhone will authenticate with the server and I know this because when I change my password on the domain the phone within 5 minutes prompts me for the new password. What settings could possibly need to be fixed in Exchange!?
