Question : IPhone to Exchange Server

  I am having problems connecting an IPhone to our Exchange Server 2003. Our Exchange server does not have a www.domain. It is all done by static IP address and port forwarding. Web Outlook does works and has for years. Here is what the IPhone is asking for:

        Email:
     Server:  
    Domain:
Username:
Password:
   Use SSL:

Here is how I answered it:
        Email: [email protected] (this is her Exchange e-mail address)
     Server:  173.15.63.166 (internet static IP address)
    Domain:   domain.local
Username:  AD Username
Password: AD Password
   Use SSL: on

Ports 443, 25 and 110 are forwarded to the Exchange Server. As stated Outlook Web works fine. Does anyone know what I am missing? The IPhone keeps comming back with an error that it cannot verify the setting.

Answer : IPhone to Exchange Server

For domain try your NetBIOS Domain Name not the Internal DNS name (IE: DOMAIN\user)
