Can't get mail encryption to work

[Dan]

Hi,
I have an enterprise CA and am trying to test mail encryption between two
users. UserA can send encrypted mail to himself as well as UserB with no
issue. UserB can send encrypted mail to himself with no issue. However,
when UserB sends encrypted mail to UserA I get the "The undelying security
system can not find the ID" error. I've looked in AD and both users have the
seemingly correct certificate listed in the 'Published Certificates' tab.
What am I missing with regard to why UserB wouldn't be able to send to UserA?
Thanks,
Dan

What happens if UserB replies to an encrypted email from UserA and tries to
encrypt it?

I get the same error as if I had sent a new message. "Your digtal ID can not
be found by the underlying security system".
Any ideas?
