Introduction to Configuring Microsoft Office Communications Server 2007 in a Multiple-Forest Environment

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.

Use a multiple forest topology in enterprises that have a need for multiple forests in Microsoft® Active Directory® directory service Domain Services to provide security or organizational boundaries. This document assumes that you have decided upon a multiple forest topology. For more guidance about when a multiple forest topology is appropriate and how to deploy, see the Microsoft Windows Server® operating system documentation.

To support a multiple-forest environment, Microsoft Office Communications Server 2007 must be deployed in only one forest in your topology, which is designated as the central forest or the resource forest. Deploying and synchronizing Communications Server 2007 across multiple forests is not supported.
