Can encrypt to correspondent, but not read encrypted message from same

Greetings,
I help out a non-profit medical clinic with their IT issues. One of the providers has encryption problems with two collegues; she can encrypt to them but can’t read any encrypted messages from them. With everyone else in the organization, encryption works fine. Everyone is using Outlook 2007 and has a Comodo free email certificate. Any ideas?

Hi,

Have you checked out the support FAQs?

It sounds like the user does not have the ‘other peoples’ certificate stored against the contact details in Outlooks address book.
