I have a client that is looking to deploy MOSS 2007 for Internet Sites on their Exchange 2003 OWA Front End server. I have found information about SPS 2003 that states it cannot coexist with Exchange 2003 on the same server; however I cannot find any such information about MOSS 2007 and Exchange, or MOSS 2007 and OWA. Does anyone know if this is a technically feasible solution and/or if this is a supported configuration?
