An anonymous participant is an external user who does not have an Active Directory identity and who is not federated with your organization. If an individual user has been enabled for Office Communications Server 2007 R2 and you chose to enable anonymous participation by using the Enforce per useroption for your global policy, you can allow the user to invite anonymous participants to meetings. For details about how to configure the global policy to use the Enforce per useroption, see Enabling and Configuring Anonymous Participation in Meetings.

To enable users to invite anonymous participants to meetings

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

  2. In the console tree, expand the forest node, and then navigate to the Standard Edition server node or Enterprise pool node that contains the user account that you want to enable for anonymous participation.

  3. Expand the pool name for the Enterprise pool or Standard Edition server, and then expand Users.

  4. In the details pane, right-click the name of the user that you want to allow to invite anonymous participants, and then click Properties.

  5. On the Communicationstab, next to Meeting settings, click Configure.

  6. In the Meeting Optionsdialog box, select the Allow anonymous participantscheck box.

    This option is enabled only if the Anonymous participantsglobal property is set to Enforce per user.
