Mustafa, I forgot to answer the second part of your post. To create the Outlook profile for RPC over HTTP, you have to be in the LAN. That requires RPC connectivity. Once you have the profile configured, you can use only HTTPS to send/receive. That can be seen as a limitation by some, but I feel it is an added level of security to ensure mailboxes cannot be downloaded to unauthorized private computers, such as home PCs. This was seen as a major plus in our company, which is very security focused.

I tried long before all steps that you listed in your mail. No chance! I followed also Microsoft Knowledge Base Article - 833401 to configure RPC over HTTP. Each time Outlook tries to connect over Port 135, not over HTTP(S). I read in the discussion group that Outlook 2003 need to be in internal network (Exchange network) to create an outlook profile. If it's true that is against the Architecture of RPC over HTTP(S)!!! I am very sure that there is another bug in Outlook 2003 for RPC over HTTP(S) connections. It is unfortunately also my work to find out this bug!
