I know that Workgroup Share does not say it can do this nor was it designed for it but it seems like it would be a great feature to added in a future update. In fact, it may not even be too difficult. The thing is that I have the Global Contact List (with read, write, edit, and delete rights) and I can add a contact to it with the digital ID attached. I then close Outlook and open it back up and look at the contact on the Global Contact List (not on my own default contact list) and it shows the digital certificate attached. I then sync with workgroup share and it completes. However, when I sync with a different client, it adds the contact but does not have the digital certificate attached.

Anybody else want this feature added?
