I had this same issue, my internal domain name was different from my external and outlook 2007 clients were initially connecting to the CAS checking the certificate which had the external domain name causing a certificate error.

I]m running into a problem where, as we roll out Office 2007 the users are prompted with security dialog boxes warning that the certificate doesn't match the server name. We currently have a certificate of the external web address (webmail ,etc.) but the internal Exchange server has a completely different name. Is there any way around this? This problem has reached the upper echelon of or organization. It was fine was it was just me, but now it has become a problem. Any help would be appreciated. -Martt ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~ ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~ -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
