Hi Scotty,

What you would need is public key of a user that you want to set encrypted
e-mail to.

Certificates have a pair of key. Public and private key. You use your
private key for digitally sign your e-mails that you send to others or use
them to decrypt encrypted e-mails send to you. For this to work the e-mail
would have to be encrypted with your's public key.

If I am not mistaken, you have Enterprise setup of your CA servers. This
setup publishes private keys in active directory for each user that you
issue certificates for Outlook should be able to find public keys there if
they were published (this will also depend on Outlook version and protocol
that it uses to connect to mail server -- e.g. MAPI).
Another option would (specially for users outside of your organization) to
create a contact in your Outlook client and manually import public key to
the contact.
