iPhone Connects With Exchange But Doesn't Download Or Send Email

I have 2 iPhones I am trying to configure with Exchange Server 2003.  The phone says the Exchange settings are verified but does not download email to the phone's inbox and does not send out email.

I can see in my DHCP leases that the iPhone is being assigned an IP.

I can access Outlook Web Access with the phone.

I am running Blackberry Enterprise Server and all the Blackberry phones work fine.  Just not the iPhones.

The network domain was originally set up without Exchange server.  Mail was accessed via an ISP's POP3 server.  The network domain name was setup as blue.local.  (I am substituting names here)  The customer's website/mail domain was bluegreen.com.  Exchange server was added to the server and the ISP eliminated from the mix.  I am wondering if the mismatch in domains is the cause of the problem. Everything functions fine except for the iPhones.  Any help here would be greatly appreciated and may help alleviate me having to find a job as a dishwasher.

Try putting your webmail's URL in the "server" field.
That works for me.  I connect to our exchange server fine inside our outside our WIFI system.

Please check your server settings by reading my Exchange 2003 / Activesync article and run the tests.
If you get errors via the test site, my article should advise you what to do to resolve them.
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

thank you alan.  i will try these as soon as i can.
Andy AndersonTechAuthor Commented:
thanks for pointing me in the right direction alan.  

i have a self issued certificate that is causing problems  (Validating certificate name   Certificate name validation failed) and evidently a DNS (?) issue to resolve (Attempting to resolve the host name autodiscover.xxxxx.com in DNS.    The Host could not be resolved )

i will review and post again shortly.

With Exchange 2003 - Autodiscover will not work.
Please re-run the test but specify manual server settings (which will aboid using Autodiscover) and that should still error on the certificate, but if you also tick the Ignore Trust for SSL check box, it should bypass the certificate test.
For the certificate, the FQDN that you are using to access the server should be the name on the certificate, so if you are accessing the server using Activesync with mail.yourdomain.com, then the certificate name should be mail.yourdomain.com (whatever you use needs to resolve in DNS externally of course, to your server's IP address).
Either re-key the certificate to match the name you ar using or use the name on the certificate, as long as it does not end in .local.
