Shared contacts list on group

[lorenzopatuzzi]

I have a group with 5 people that has a group mailbox like sales@contoso.com, I would like that every member can look and add contact to the contact list of that mailbox...

Is it possibile ? Is there a way to have a shared contact list between member of the same group ?

Groups don't expose the Contacts folder, better use a Shared mailbox for this.
