We are running Exchange 2003 behind 2000 ISA on a separate server. I had OWA setup and working. Well it still seems to work but It doesn't ask the user for a certificate anymore. We've cleared out all old certificates and tried to sign on with a computer that has never accessed our OWA site. It just goes straight to the Form based authentication page. Any idea why the certificate don't pop up anymore? _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Both the individual sending this e-mail and Cross Oil Refining and Marketing Inc. intend that this electronic message be used exclusively by the individual or entity to which it is intended to be addressed.This message may contain information that is privileged, confidential and thereby exempt and protected from unauthorized disclosure under applicable law.
