Unfortunatly I have a localized version of outlook, where "Outlook Anywhere"
is never mentioned.
In the system control panel, i have the email settings icon, i open the
correct profile, then, in the email tab i have "Microsoft Exchange", i click
on "Change" button (the third one), then in Advanced (bottom right),
Connection tab i see a section on the bottom of the dialog, wich is called
The flag "Connect to Exchange through Internet" is checked. Clicking on the
button "Exchange proxy settings" i see the public dns name of my exchange
The authentication is set to 'base authentication'.
So i guess the following thought, correct me if i'm wrong.
Configuring outlook in order to access an exchange server is a matter of
proxying rather than accessing directly.
The client is first connecting to a proxy, and from that to the inner server
using the server's netbios name (well proxy and server are actually the same
machine). That's why you keep indicating the server with it is internal
netbios-name. The public dns name is actually the name of the proxy for the
rpc over https encapsulation.
