1.Outlook 2003 vs Outlook 2003 RPC/HTTP

Hi all,

would like to confirm what the best option is, company has 2 sites, all the 
Exchange servers are in Site 1 and 500 users from site 2 will connect to 
those servers, communication between sites is ok (around) 8 Mbps, my 
question is, would make sense to deploy a front end in site 2 and make the 
users RPC/HTTP enabled? or MAPI with cache opcion enabled?

mailbox server is 2 CPUs and 4 Gbs of memory serving 1500 users.

i am a little concern in the way that the exchange servers at site 1 will 
support all the MAPI connections thats why we are thinking that adding a FE 
in the second site may reduce the overload in the exchange central servers

regards

3.Outlook 2003 on Windows 2003: RPC over HTTP?

Hi!
We deployed Exchange 2003 based on Windows 2003 AD. Our Windows XP user can 
access Exchange Server by using RPC over HTTP without any problem.

We have Windows 2003 on which we installed Outlook 
2003 with SP1. Our users will use RPC over HTTP from this client also. 
Unfortunately they cannot connect from this computer to Exchnage by using RPC 
over HTTP. They have no problem with OWA connections.

Is there any restrictions if a Windows 2003 Server is deployed as Outlook 
2003 client?  Can we use Outlook 2003 on Windows 2003 Server for RPC over 
HTTP 
connections? How can we fix this problem?

Best Regards
Mustafa

5.Exchange 2003, Outlook 2003, and RPC-HTTP

I've been working my way through setting up a RPC-HTTP connection between 
Outlook 2003 and Exchange 2003.  It's to the point that an internal (within 
the local network and domain) RPC-HTTP connection seems to work fine.  Also, 
I've used IE to connect to Exchange's RPC folder (example - 
https://mail.exchangeserver.com/rpc and then filled out a challenge box for 
user name and password).  The proper error page shows up (403.2 Forbidden: 
Read access is denied) and everything seems fine.
But Outlook can't find the server.  I've made repeated attempts to connect 
with Outlook in rpc diagnostic mode (DOS box - "outlook /rpcdiag") and get 
the challenge box for user name and pass; but it never finds an Exchange 
server.  I've tried to put the user name in different formats: 
domain_name\user_name, server_name\user_name, just user_name, and so on; just 
to see if it mattered.
There is a PIX 501 firewall sitting between external clients and the 
Exchange server.  The PIX is setup to allow/pass traffic from ports 80 (HTTP) 
and 443(HTTPS) to the Exchange server.  Since the RPC packets are being moved 
via HTTP, I have not punch a hole for RPC in the firewall.
The Exchange I'm using is part of the Small Business Server 2003 package.  
SBS made it easy to setup the Exchange side of RPC-HTTP (a wizard and a check 
box later it was ready) and I've gone through different 'How to' FAQs that 
verified Exchange's setting are correct.  So I'm left with the firewall 
and/or the client.

Any help on this would be great.

Thanks.
