A corporate environment includes Exchange Server 2007 SP2 and an Active Directory Domain Services (AD DS) domain named contoso.com. The Client Access server, cas01.contoso.com, has an SSL certificate. The SSL certificate includes mail.contoso.com and autodiscover.contoso.com. Outlook Anywhere is disabled. Client computers run Microsoft Office Outlook 2007. After you transition the Exchange Server environment to Exchange Server 2010, Outlook displays a warning message indicating that the SSL certificate is not trusted for connections to cas01.contoso.com. You need to recommend an approach to resolving the problem.
