Office Communicator 2007 R2 Group Policy Settings

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

One way to provide the appropriate registry settings for each user when you are deploying Office Communicator 2007 R2 is to define Group Policy settings by using an administrative template (.adm) file. Administrative template files contain specific information about which Group Policy settings the application implements, where policies are stored, and how to configure policies.

To define Group Policy settings by using the Communicator 2007 R2 administrative template file

  1. Copy the Communicator.adm file from your distribution disk to the %windir%/inf folder.

  2. Use Microsoft Management Console Group Policy Object Editor to enable or disable specific policy settings.

You can deploy Communicator 2007 R2 Group Policies without affecting users who are running Communicator 2005.

Group Policy Precedence

Some Communicator 2007 R2 features and behavior can be configured by the administrator who is using Office Communications Server 2007 R2 in-band provisioning, or by the user through the Communicator 2007 R2 Options dialog box. However, Group Policy settings take precedence over both methods.

Table 1 summarizes the order in which settings take precedence when a conflict occurs.
