Can the Exchange 2010 CAS role be installed on Windows Server 2008 R2 Core installation? If so, is there any documentation provided by Microsoft that verifies that this is valid and that it is a supported type of installation? All other roles will be on a full installation of 2008 R2. Thanks in advance.

While you can install the pre-req's for CAS on Server Core Exchange will not install on a Core installation of 2008 or 2008R2Matt Cline - MCSE+M, MCITP: EA | EMA (2007, 2010) | Lync 2010 Blog: exchangeadventures.wordpress.com
