Understand Presence & Privacy Relationships:
Your presence information includes your availability status (such as available or away), presence indicator (such as green, yellow, or red), schedule, location, and personal and out-of-office notes. 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.
Note: Non-buddies when in Enhanced Privacy Mode, and blocked contacts will see only your display name and email address
