1. Make sure both the sender and the recipient need to have a digital certificate.

2. The intended recipient needs to have sent you at least one message with a digital signature. Then you add the contact's digital ID certificate to his/ her contact item in your Address Book, Right-click the sender's name in the From fields, and then click Add to Outlook Contacts.
