The sales team at a client’s company are using RPC over HTTP in outlook 2007 to connect to their emails from home. In outlook 2003 this always has and still does work fine. However they are now getting a certificate error (attached)
The interesting this is this is only happening in this version of outlook for machines that are attached to the corporate domain. If the machine is in a workgroup there is no issue.
The MSSTD proxy is set to the CN of the certificate but still we are getting errors. Short of turning the proxy feature off within exchange I am out of ideas. Any help would be much appreciated.
