I'm trying to configure an account in Outlook using the Zimbra Collaboration Server connector and it fails to create the account saying:

"Your account could not be validated against the Zimbra server.

Unable to establish a secure connection to the server because the identity of the server could not be verified due to a problem with the server's certificate."

The problem is, the administrator is not going to fix the certificate. How can I force Outlook and the Zimbra connector to let me create the account anyways? I have tried installing the certificate in Windows even in the trusted root certification authority, but it still won't let me create this account...
