Hi Amir,
Thanks for your answer. Now i understand a little more how Entourage connect and authenticate itself. We use an external certificate and have changed settings for CAS/Webvirtual directories to correspond to the new external fqdn (we have also created a zone in our internal dns to answer for this fqdn). It works fine for our Outlook clients but the Entourage can't still access the individual mailbox, and why does public folders work? Is there some things to take in consider when we use a certificate from an external CA? We are only running one multi-role E2K7 server with HubT, CAs and mailbox roles running. We do not have any edge or ISA server installed yet in our environment.
We can send you a print of a network trace where we see that the entourage client really authenticates itself and the user logs on but it will not list the contents inside Entourage 2004. We will try your suggestions, and come back to you with the results. We are very thankful if you meanwhile have any more thoughts about our problem when reading this reply. Thanks!
Kr,
Richard
