I'm a little confused when it comes to configuring Outlook Anywhere, and I have a few questions. My setup: I have 2 mailbox store servers that are clustered. The cluster name, and the name that users on the inside use to connect to their mailboxes is "tesscms.mydomain.org". I have 1 CAS server, where Outlook Anywhere is enabled, and it is named "gvcas.mydomain.org". What external host name do I use when enabling Outlook Anywhere in Exchange 2007? Can it be anything (I currenlty have it set as "cas.mydomain.org")? I also have a UC cert (from Digicert) that is installed on the CAS server and I have gvcas.mydomain.org, cas.mydomain.org, tesscms.mydomain.org, & autodiscover.mydomain.org as the SANs. Also, what URL do I use on the client side when configuring Outlook?
