I have a Server 2003 R2 Standard Edition SP2, with Exchange System Version: 6.5.7638.1 server setup and I am trying to get my iPhone 3G to sync but when going to https://myexchange.mydomain.com/oma
"Outlook(r) Mobile Access is supported only on Microsoft(r) Exchange Server 2003. Currently your mailbox is stored on an older version of Exchange server. Please contact your system administrator for additional assistance."
According to MS (http://support.microsoft.com/kb/158530
) Build 6.5.7638 is 2003 SP2.
I am hoping someone can assist.
