My company uses Exchange and the Outlook Web App for access outside of work. We recently had certificates change after our admin installed new Exchange servers. The OWA address now shows that the certificate has been revoked but the site is actually good. In IE I can just turn off checking for revocation in the settings and still get to the site but in Firefox (which I use pretty much exclusively as well as a number of other people in my company) I cannot add any kind of exception for this or anything. I also tried just generically unchecking the "Query OCSP responder servers to confirm the current validity of certificates" option but I still am not allowed to continue to the URL. Please help as I need to use our web app quite often for email access and I know the site is ok.
