I need to set my HR staff up to send encrypted emails on adhoc cases to any users internally or externally. Some users are not computer savvy so they will not have a certificate. We are not so much concerned with receiving encrypted email but are more concerned with sending out encrypted email. We are running Exchange 2010 SP3 and Office 2010. I had download a free certificate from symanetic but I am not allow to send it to a users because she does not have a certificate. Is the only way to send out encrypted email is that both the sender and the receiver must have digital certificate?
I am hoping I can just send an encrypted email out to a user and be able to send them my public key.
