How can I set up Mac Outlook 2011 so that it will use the Exchange 2010 server internally (by hostname) & connect to the Exchange server using https address externally?

How can I set up Mac Outlook 2011 so that it will use the Exchange 2010 server internally (using the Exchange server's hostname) & connect to the Exchange server using https address externally?

Outlook 2007 and Outlook 2010 for Windows can be set up this way; can Outlook 2011 for a Mac also be set up in this way?

The Mac is using OS X version 10.6.4.

The Exchange 2010 server is set up with Auto Discover.

The problem that I'm having is that when I configure Outlook 2011 for Macs to connect to the Exchange Server using a hostname or Fully Qualified Domain Name, the laptop won't connect to the Exchange server over the internet.

When I configure Outlook 2011 for Macs to use the Outlook Web Access (OWA) address, the laptop will connect to the Exchange server just fine from outside of the office but then won't connect to the Exchange server while inside of the office.

I'm looking for a solution that it will use the Exchange 2010 server internally (using the Exchange server's hostname) & connect to the Exchange server using https address externally.

This can be set up quite easily on Windows computers running Outlook 2007 or Outlook 2010.

Why can't the Macs connect to the CAS server internally?  A split-DNS issue maybe?  Is your internal domain name different from your external domain name?
