Military CAC certificates will not publish to Outlook 2007 on a Win XP system. This happened after the client received a new CAC card. We have renamed the windows profile and created a new one, removed and replaced the old certs several times, tried recovering old certs. We have also tried creating a new Outlook profile. None of this has worked. We can get the certs to publish on a different PC, which indicates that the CAC is good and not damaged. This act like a registry problem, but I cannot find the registry settings that would be affected.
