We have Exchange 2010 server and someone has installed a third party certificate on the exchange server so we have a legit webmail url (owa). This works without any problems but the internal users now have the problem that when outlook starts they get a certificate error message that the certificate is not trusted. And if they click on 'view certificate' they see the third party certificate. So it looks like all the services are assigned to that third party certificate.
So I have created a new self signed exchange certificate and moved the services SMTP, IMAP & POP and rebooted the server. But the clients are still getting this error. Do I missing something?
