Hi All, I understand that autodiscovery service should be published for internet clients to get availability,OAB etc features available. We have one certificate for mail.contoso.com and we have installed certificated and did not configure autodiscovery.constoso.com as we do not have SAN. I have observed that my OUtlook anyhwere shows the Free/busy, OAB etc information. could someone explain the relationship well Thanks Uday
