Everytime we go to a https site IE drops down the message... "Internet Explorer has blocked this website from displaying content with security certificate errors." If you click on and select display blocked content the page displays properly. Is there a certificate from the Ironport that needs to be installed in IE? How do we prevent this message and have the web page display properly?
The right way to deal with this is to put a signing cert that your machines trust on the ironport. (eg. If you have a cert authority installed on your network, generate an intermediate cert and put that on your Ironport)
We don't have a certificate authority... however it looks like if we download the cert from the Ironport and install it locally in IE it fixes the issue. I believe we can do this through a GPO but need to research a little more. Thanks!
