I have Exchange 2010 SP3 with Godaddy wildcard Certificate "*.domain.com". Certificate is working fine for both outlook anywhere, OWA but some internal user got some certificate pop up for "mail.domain.com" which is external domain name . when I click on view certificate , the certificate untrusted is "Watchguard Fireware Web CA".
I have tried "Set-ClienAceessServer - identity ServerName -autodiscoverserviceInternalUri "https://mail.domain.com/autodiscover/autodiscover.xml".
but , some internal clients are still looking for "mail.domain.com" via " Fireware Web CA"
Please , advise
