I have exchange server 2013 installed with Active Directory CA for the certificate. Windows XP running Outlook 2010 conncet without problems after applying Office sp2. All my windows 7 running office 2010 machines fail to connect even after applying the office Sp2. The following message is given:
There is a problem with the proxy server's security certificate.
The name on the security certificate is invalid or does not match the name of the target site <domain URL>
Outlook is unable to connect to the proxy server (Error Code 0)
