Question : Exchange 2003 with 2 certificates

Set up is ISA 2004 (Listener set up for SSL) and exchange 2003 at backend. I do not think it is possible but worth the question. Does anyone if any one know how you can have two certificates for the one site. Eg webmail.domain1.com and webmail.domain2.com simultaneously. I only need this for a short period of time to allow people to adjust to the domain change.

Answer : Exchange 2003 with 2 certificates

what you are looking for is called a certificate with SAN (subject alternate names) or UCC

the idea is not to have one IIS Site with more than one certificate assigned to it but rather ONE certificate with multiple fqdns
