Outlook unable to connect to proxy server (error code 20)

This error has been poping up on all my computers that are using a ssl certificate created for our business for user to connect to our exchange server via https:// connection.

Cannot find anything online to help me with this.  Any help would be greatly appreciated.

If your exchange server is running on service pack 1, you may need to install service pack 2.

The info is resourceful, however i do not understand what i am to do.  Because i never dealt with ssl's other then installing them.  Would it be easier for me to create a new certficate or update the old.  This issue is causing huge problems for me.  When i look at the CERT it says it is set to expire in 2013.  So i have no clue how to trouble shoot this issue.
