I created a contact list to be shared by six users. The contacts are all there and everyone can access them and use them.

Here's the problem: Contacts in a user's personal contact list keep a 'history' in the "Contact" tab under "Show", "Activities". Contacts in the shared contact list do not seem to keep the history...at least I see no "Activities" option in "Show".

Is there a way to share a contact list (address book) where each user's activity will be included in the contact history?
