I have a new exchange 2007 box on Windows 2008 R2, email is flowing internally and externally. Outlook Web Access is working fine. I would like to connect my iPhone and Outlook 2007/2010 to our server for email connectivity. When I setup the Outlook client, I add the internal IP address as the exchange server, my username, I insert the correct settings in the Exchange Proxy settings, but cannot get the clients to connect.
What are your thoughts on this? What should I look for?
Thanks in advance for your help.
