        It's also very easy to manage via a GPO for your corporate
systems (i.e., laptops).  
        
        It does present challenges for non-corporate managed systems,
but why would you want them hitting you via anything other than OWA
anyhow?  If they are non-managed (or unmanaged) then they should be
classified as untrustworthy WRT virus, spyware, malware, and/or other
security concerns.

                However, managing the PKI yourself is much more secure,
and isn't that why you're using SSL in the first place?

                        Setting up RPC over HTTPS makes no difference to
the  current users or the way that your network currently operates.
Until you  are ready to deploy the feature the users will not see any
difference.  
                        
                         
                         
                        One server can act as the RPC over HTTPS server
for both  internal and external clients. However if you don't want to
change the client  configuration each time they come in to the office,
use a generic name for the  certificate and name of the server
(mail.domain.com or something like that)  and then configure split DNS. 
                        Split DNS will allow you to resolve
mail.domain.com to the internal IP address on your network, while
mail.domain.com will resolve to the public IP address outside.  
                        
                        That will make it totally transparent to the
users. I  have deployed it in the past where the first the users knew of
it was when  they got email when they started Outlook before connecting
to the VPN.  
                        
                         
                         
                        The only other suggestion I strongly recommend
is to use  a real purchased certificate instead of a home grown
certificate. While you  can do it with a self issued certificate, it
causes more work and headaches,  whereas a cheap purchased certificate
(rapidssl starterssl is perfect) gets  round a lot of the problems.

                        I am planning on implementing rpc over http
                        I  have dc server and exchange server, will all
users
                        be forced  to use rpc over http? 
                        
                        
                        When I make registry changes on  the exchange
server for RPC proxy
                        does that effect my current RPC  authentication
or does that effect only
                        rpc over http  requests?
                         
                        
                        Can one  exchange server act as a internal
server for lan clients
                        and simultaneously  act as a external rpc over
http server
                        

                
                
                 
                 
                
                Thanks in advance,  Jeff
