clients on XP and windows 7 (outlook 2010) have received a security Alert stating "The security certificate has expired or is not yet valid". The certificate has expired. I have created a new one, but they still get the same alert.
I have gone onto the server and deleted the expired certificate, but still they get the alert. I have picked one client to work on, I have removed the certificate from the client computer, rebooted, but after opening outlook the security alert returns.
Any ideas how to make the clients use the new certificate or at least stop looking at the expired certificate.
