Greetings list! I have recently deployed a new Exchange CCR cluster with a seperate CAS. The client has their own SSL certificate that resolves to mail.domainame.com. I configured this certificate for OWA and used Microsoft KB article 940726 to configure the autodiscover URL so the users don't get the certificate error when Outlook 2007 autoconfigured Outlook. However, after I made the recommended changes, including the step listed under ?More Information" the users are still recieving the invalid server name error, when the autodiscover service configured outlook. How do I properly configure the URL for the autodiscover service so the URL with the correct SSL certificate is provided to the Outlook client? I would like to note that we have an internal DNS zone setup for the client's public domain name that resolved the CAS FQDN (internal) to the correct internal IP. Thanks, Eric Hanke
