Hi James:
Thanks for posting here.
Generally speaking, both methods are secure. However, I suggest you use the
VPN method since all the traffic is transferred through a virtual VPN
tunnel.
Can I assume that you haven't enabled the RPC over HTTPS on the SBS Server?
If so, you can perform the steps described in the following KB article to
enable the RPC over HTTP:
How to configure RPC over HTTP on a single server in Exchange Server 2003
http://support.microsoft.com/kb/833401#9
Based on my knowledge, in most cases, the RPC over HTTPS issue of the SBS
2003 servers could be caused by the certificate trust. The web server
certificate issued by the SBS CEICW is not trusted by the Outlook client
natively. When we connect to the SBS server through RPC over HTTPS, since
there is no mechanism to prompt the certificate security alert (as IE does)
to let the user to confirm the connection, if the certificate is not
trusted by the client computer, the RPC-HTTPS would not be established.
Here, I suggest you refer to the instructions in RWW site and then
reconfigure the remote Outlook client. You may open Internet Explorer,
access https://FQDN/remote and input the credentials. Click the link
'Outlook via Internet'. After doing the steps, will you be able to
establish the RPC-HTTPS connection?
More info:

connections from Office Outlook 2003 to Exchange Server 2003 (884506)

Hope the above info helps. Please feel free to let me know if you have any
questions.
Have a nice day!

| Ok, this one seems wierd to me.
|
| If I'm out of the office, I open outlook (after following all the steps
that
| the Wizard posted in the 'setup outlook for web access document'), and it
| won't connect. I can connect via the Web Outlook using the https:// from
| anywhere.
|
| As soon as I open the Connect to SBS Server, outlook starts working fine.
|
| 1) Is it safe to use outlook without connecting via the VPN (I'm assuming
| that's what the connect to SBS Server app is)
| 2) What can I do to troubleshoot this?
|
| thanks in advance,
|
| James
