I have OWA set up on a a SBS2008 64 bit server.
It uses a Godaddy secure ceertificate for OWA access.
Everyone is fine, except one user for OWA access from their homes.
Even on this user, for Firefox it works fine. It's just Internet Explorer 8 that throws up the
"There is a problem with this website's security certificate" warning.
I have installed the certificate, but it makes no difference, it still throws up teh error.
It's obviously some problem with the local PC and probably some setting in Internet Explorer, as everyone else is fine.
