Hi AllRunning a W2008 server with enterprise CA. Running Exchange 2007, hosting OWA for multiple domains. DNS configured to point all domains to external IP, ok. Can access OWA fine for each domain using https://mail.domain.com/owa - but with certificate erors that say "the securitycertificatepresented by this website was issued for a different website's address. This is because the single certificate hosted by the enterprise CA is for the local server. Since one external IP address services all domains, I need a single certificate to reference all of the URLs used to access OWA for the different domains. Not even sure if this is possible, or if there is a way to use multiple certificates?Any help appreciated.

Hi, You may consider wildcard certificate.
