I am trying to get Outlook Anywhere to work with Server 2008 / Exchange 2007 but as I understand it requires you to install a valid certificate. I have been researching this and where there is alot of info out there none of them seem to get me to a complete solution.

Yes, its recommended if you are going to have remote OL users to get a SAN Certificate. I prefer Go Daddy's Multi Domain Cert as it works and its affordable. Jim McBee has great blog post about this, http://mostlyexchange.blogspot.com/2007/04/godaddy-subject-alternate-name.htmlMVP Exchange Server
