Privacy relationships control how much of your presence information you want your contacts to see. Contacts are assigned to five different relationships and each relationship provides access to a different set of information. For example, all new contacts are automatically listed as Colleagues in your organizations when you add them. Therefore they can see more of your information than External Contacts but less than Friends and Family.

iii. Presence and Privacy Relationships
The following table shows which presence information attributes are available for a given privacy relationship. Contacts with whom you have a Workgroup relationship are likely to be important. Only these contacts can interrupt you when you have set your status to Do Not Disturb.
