Cannot see new e-mails on iphone 4 connected to exchange 2003.
The setup:
Windows 2003 SBS SP2
Exchange Server 2003 SP2
--Function level is at Native Mode
--Exchange vDir for mobile access is set to: /exchange-oma
DC - AD
--Function level is at Windows 2000 Native
Internal Outlook clients connect just fine and can send / receive through the Exchange server.
The business gateway is set to forward ports 443 and 25 to the Server IP.
The scenario:
This is the strangest thing but it is happening.
I can add a new account through the iPhone for the exchange server, accept the SSL certificate, and off it goes.
However, I can only see read e-mails on the inbox, sent items, etc.
If any items are new (New emails) they will not show up on the iPhone even if I manually force it to refresh.
Here's where the strange happens: I go to the Exchange OWA and click on the new message to read it... as soon as this happens I can refresh the iPhone and the newly read message shows up on the iphone as a read email.
Any thoughts?
Things I've tried:
Restored the iPhone 4 and updated the software to the latest iOS (4.3.5)
Checked and re-checked IIS permissions for the OMA and Default Web Site.. Ok.
Cross-referenced another server from another client with identical setup and theirs works fine, this one does not..
I'm lost and need some help.
