I have a SBS trial machine set up to test RPC over HTTP with Outlook 2003/XP SP2 clients. Running into a few problems even after searching the useful advice on here.
I set it up first with just the external ip address, but realised it needs dns. Contacted the ISP and got them to set that up.
The certificate seems to work fine, once its installed I go straight into https://www
If I go to the rpc page (?) I get the required error message (access forbidden).
Its a single server so I've double checked the registry entries and they all seem ok.
I ended up having problems connecting with outlook even on the network. I got the error message could not open mail folders and something about OST and terminal services???
When you enter the URL in outlook to connect to, should that be https://www.external.name.com
Should the proxy be msstd:www.external.name.com
