Zane -

1) Client should be configured in the Outlook profile for "Exchange Server
Settings" just like it would be if it were on the local network (ie - put in
the real server name, real mailbox name, etc). However, to enable RPC/HTTP
connection from the client, you will need to click on "More Settings", then
"Connection" tab. And at the bottom of this tab, you will see a checkbox to
connect over the internet and an "Exchange Proxy Settings" button. Inside
the Exchange Proxy Settings dialog is where you need to specify the
"as-seen-from-the-Internet" info. Put in the FQDN of your RPCProxy server as
seen from the internet (make sure the FQDN matches what is actually DNS
resolveable *AND* what is listed on the certificate).

The Outlook client will first establish an RPC/HTTP connection with the
settings in that Exchange Proxy Settings dialog, and will then tunnel across
this connection to the real back-end server with the RPC settings defined on
"Exchange Server Settings" (this part is just like for any Outlook profile
using RPC over TCP).

2) On the FE you need to have RPCProxy component from Add/Remove. You need
to have Exchange 2003 Sp1 (if you want to use the Exchange 2003 SP1 managed
topology: http://blogs.msdn.com/evand/archive/2004/06/09/152016.aspx). On
the BE it's just regular Exchange, albeit of course all of these OS
(including the GCs) have to be Windows 2003.
