Anyone else having this problem?: Leopard 10.5 Entourage 2004 with all updates Exchange 2003 Server self-published certificate In Tiger 10.4, Entourage was able to connect to the Exchange Server without any problems. Since I upgraded to Leopard 10.5, Entourage now fails to connect with the error message "Unable to establish a secure connection to servername.com because the correct root certificate is not installed." I've tried removing and reinstalling the certificate, but the old X509Anchors keychain is gone and recreating it doesn't help. Any ideas? I don't especially want to spend hundreds of dollars buying a certificate from Verisign when there is nothing wrong with the self-published certificate I already have. EDIT: Forgot to mention: If I click OK, I can connect and send/receive mail, etc. I just want to know if there is a way to get rid of the stupid error message.
