Using Outlook 07 via HTTP

I am trying to set up Outlook 07 to be available via HTTP.

I have succeeded in doing this when using a machine within our network.  However when I use a machine that is not on our network I get the following message:

"Outlook cannot log on.  Verify that you are connected to the network and are using the proper server and mailbox name.  The conmnection to Microsoft Exchange is unavailable.  Outlook must be online or connected to complete this action"

It seems as though it cannot contact the exchange server?  I have tried identifying the Exchnage server by name, internal and external IP address but with no luck.

Any help would be gratefully recieved.

Thanks in advance.

The subkey mentioned in that article does not appear in my registry.  I am a little confused.  I would have thought that if the problem was the one mentioned in this article then using http within my network would not have worked or would it?
What is listed under HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\RPC ? Do you have the RPC? Try creating that key
You are doing this fix on the client computer correct?
Yes on a client computer.  But there is no RPC key under HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\

Shall I create the RPC key?
Back up the registry and give it a go, worst case senario you will just have to restore the registry backup, it shouldn't cause any serious damage.

Thanks for all of your advice.

My problem was that the correct certificate was not installed on the client PC.
