Hey guys,

The articles I did on RPC over HTTP applied to a beta version of
Outlook. In the final version, you do not need to have Exchange RPC
available to setup the user profile.

Hi Raj,

To your previous question:
No, I cannot any certificate related information message, if I try to
create an RPC over HTTP profile. Outlook tries to connect over RPC port
(NOT through RPC over HTTP) to connect to Exchange.

To your last message:
Is it really true that RPC over HTTP profile can only be created? 

I'm disagree with you that this is a security advantage. In this case,
person who works in home office or in another company and wants to have
RPC over HTTP profile, must bring his/her computer to my LAN to have an
RPC over HTTP profile!!! What a wonderful design of Microsoft!!!
That is really unbelievable. 
I think, Steve has right that RPC over HTTP needs still port 135 to
connect Exchange.  If yes, this profile should be called RPC over

I didn't read in any Microsoft documents about it. It seems that
doesn't publish this "open secret"?! Or dou you know any official
Microsoft document about it?

Best Regards
