I installed a new Exchange server certificate on my Exchange server running Windows 2008 R2 and Exchange 2010 SP1. I followed Go Daddy's instructions and everything went fine until I came to the end and a dialog box came up asking "Do you want to enforce SSL communication on the root web site? ". Unfortunately I clicked on yes. The certificate installed OK and no problems with my OWA site. However all of my network users are now having popup security alerts on their PC's about the certificate not matching (our network domain is .local and the certificate for the OWA site is .org). I tried to fix this popup alert problem by going into IIS Manager going to the default web site and unchecking require SSL in SSL settings. I restarted the IIS service and still the pop ups persist. Am I going in the wrong direction with this or do I need to reboot the server? Also are there any components besides OWA that need to remain checked?
