Anonymous participation in meetings enables anonymous users, that is, users whose identity is verified through the meeting or conference key only, to join your meetings. By default, all users are disallowed from inviting anonymous users to participate in a meeting. You control who can invite anonymous users by setting options at three levels:

To configure the global policy for anonymous participation in meetings

  1. Log on to an Office Communications Server 2007 R2 Standard Edition or Enterprise Edition server or a server with Office Communications Server 2007 R2 installed as a member of the RTCUniversalServerAdmins group or a group with equivalent user rights.

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

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

  4. Click the Meetingstab.

  5. In the Anonymous participantsdrop-down list box, click the global policy that you want to enforce:

    • Allow users to invite anonymous participants. This policy allows all users in your organization to invite anonymous users to meetings.

    • Disallow users from inviting anonymous participants. This policy prevents all users in your organization from inviting anonymous users to meetings.

    • Enforce per user. This policy enables you to configure individual user accounts to invite anonymous users. All other users are prevented from inviting anonymous users.

  6. If an appropriate global meeting policy has not been assigned, you can configure one as follows:

    • Under Policy Settings, in the Global policydrop-down list box, click the name of the policy that you want to use for meetings.

    • To view or modify a policy, under Policy definition, click the name of the policy, click Edit, modify the policy, as appropriate, and then click OK.
