Before setting up collaborative storage policies, you need to understand the two types of collaborative storage policies and the differences between the two.
A Group Collaborative Storage policy creates storage for a group when a Group object is created in an organizational unit where the policy is associated. For example, if a cross-functional team named HEALTHFAIR2014 is created in an organizational unit associated with the Group Collaborative Storage policy, the collaborative storage area is created when the group is created.
A Container Collaborative Storage policy grants access to collaborative storage when a new User object is added to an organizational unit where the policy is associated. For example, if user BSMITH is added to an organizational unit that had an associated Container policy, BSMITH is granted access to the collaborative storage area. Furthermore, if the template associated with the policy is structured with a -MEMBER- Group object, the user is given a personal storage area within the collaborative storage area.
