Hi all- In order to support Exchange 2007, we need to use a Subject Alternative Names (SAN) SSL certificate. I assume, since you can publish Exchange 2007 on ISA 2006, that ISA 2006 (Standard, SP1) must support these SAN SSL certificates. Is that a correct assumption? (My Exchange admin just found an older document that says ISA 2006 won't support them.)
