I currently have Outlook 2007 and Exchange 2003 on SBS 2003 with latest service packs / hotfixes.
Everything works fine via my network and VPN. I can also successfully use OWA from my machine without any certificate errors.
I have now tried to connect HTTP/RPC and continue to get errors. I have configured my Outlook as https://server.domain.com and msstd:server.domain.com where server.domain.com = the same thing I use for OWA. I have NTLM Auth. turned on.
I do NOT have ISA installed and would prefer not to. I have port 443 forwarded to my Exchanger server and again this works fine for OWA. I have read where this will work as I have it configured but I'm having no luck at all.
