I am new at this company and before I started they retired one of thier mail servers. Now the server that is gone "MLEX02" users on VPN are getting a SSL Cert warning that it is expired and to trust the cert. Last month I did renew the SSL Cert on MLEX01. The configuration I walked into here was that one mail server was up and running MLEX01 but, it has referances on it pointing to a mail server called MLEX02 which is gone. How do I disable the cert error looking for the server that is gone? Thanks Marc

Clients don't randomly generate certificate prompts. They must be connecting to something with that certificate request. That either means there is something in their configuration that is using that old server, or the server wasn't removed correctly. However you haven't provided any version information, so it is hard to say what it could be. Depending on version it could be autodiscover, public folders, OAB distribution. It could be something as silly as a hosts file on the workstations which means they are connecting to the wrong system. Not enough information to say for sure.
