Users can poll the presence of other users who are not in their contact lists. For example, an e-mail client might poll for the presence of people who have sent a user e-mail but who are not in the user’s contact list. You can control whether users who are not in the user’s contact list can view presence information.

Important:
This setting affects only user accounts that are not enabled for enhanced presence. Office Communications Server 2007 and Office Communications Server 2007 R2 users who are enabled for enhanced presence are not controlled by this setting.

To enable or disable viewing of presence information for noncontacts

  1. Open the Office Communications Server 2007 R2 snap-in.

  2. In the console tree, right-click the forest node, click Properties, and then click Global Properties.

  3. On the Usertab, do one of the following:

    • To make it possible for noncontacts to view presence information, select the Enable users to view presence information for non contactscheck box.

    • To prevent noncontacts to view presence information, clear the Enable users to view presence information for non contactscheck box.
