I updated our SSL Cert for our Exchange 2003 server back in January. I believe the current certificate was due to expire yesterday (April 5th, 2009). As of this morning, I am receiving the following message on Entourage clients which have been configured with the option "This LDAP server requires a secure conection(SSL)". I do not encounter certificate errors when I connect to the Exchange server via OWA. I have verified on my exchange server that the current certificate installed for the 'Default Web Site' is valid, it expires on April 5th, 2011. Is there perhaps another location in which I missed updating the cert? Any info would be greatly appreciated. I am attaching a screen cap of the error message which Entourage is producing.
