I am trying to integrate the 3G iPhones with Exchange 2003 SP2 and have hit a brick wall. We currently use Blackberry devices and have a dedicated BES server for this, these work fine and have done for years.
We are also using OWA which is sitting behind a Windows ISA 2006 appliance. This has been in place for 2 years and also works fine. Anyone accessing the published OWA URL (https://owa.domain.com/exchange) is advised that "This certificate cannot be verified up to a trusted certification Authority" however clicking on continue when in Internet Explorer does take the user to the logon screen where they are able to login and send/read e-mails via OWA. This has always been the case and we are happy with this as there is only a very small number of users allowed this kind of access. I am assuming this is a self signed certificate?
I have read so many different document guides regarding implement iPhones and I've gone around in circles. Some mentioned using IMAP, some POP3. My understanding is that the 3G handsets (with v2.0) do not have to use POP3 or IMAP. Is this correct?
When I am trying to configure my iPhone where should I point the Server settings to from within the Exchange Mail setup on the iPhone? Is it owa.mydomain.com/exchange?
Here is a run down of what I have done so far.
Enabled "Exchange Outlook Mobile Access" from within Mobile Services on our Back-end Exchange Server and also ticked "Enable unsupported devices".
Installed Mobile ActiSync on the Backend Exchange Server and IIS now shows a few new websites within the Default Website
Installed the iPhone Configuration Web Utility on my laptop
Exported the cert.pfx and installed manually on a laptop
Where exactly am I going wrong? Have I missed something obvious?
