Microsoft Office Communications Server 2007 R2 offers many features that are attractive to business users. Instant messaging (IM) with presence, Web Conferencing, and federation with business partners help users to efficiently conduct meetings without needing a formal conference facility. Edge services enable telecommuting by providing remote users, including business partners, access to meetings, messaging, and presence information.

This walkthrough explains how to deploy Office Communications Server 2007 R2 for an organization that has fewer than 5000 users. This document is targeted at IT professionals who have experience working with Microsoft server technologies, networking technologies, and complex Active Directory topologies.

The deployment described in this paper includes IM, presence, audio/video (A/V) conferencing, and Web conferencing. We assume that this deployment is not mission-critical, and so backup and failover are beyond the scope of the paper. For details about deploying Office Communications Server 2007 R2 Enterprise Voice and integrating Exchange 2007 Unified Messaging, see the Deploying Enterprise Voicedocumentation and Integration with Exchange Server Unified Messagingin the Planning and Architecture documentation.
