Development

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.

The Microsoft Office Communications group provides a wide variety of Office and Unified Communications SDKs and API sets. Detailed application development documentation is beyond of scope of this guide. Instead, the following topics provide high-level overviews and include links to the more detailed developer documentation and resources that are hosted at Microsoft Developer Network (MSDN).
