Microsoft Exchange Server
For maximum productivity, information workers need to be able to switch instantly among e-mail, instant messaging, voice telephony, and other communication modes based on rich presence information. Exchange Server and Microsoft® Lync™ Server 2010 work together by providing a unified contact list, integrated capabilities, and shared presence data to provide a seamless communication experience. Microsoft SharePoint Server
SharePoint is all about collaboration, and collaboration requires communication. Lync Server 2010 gives workers more ways to interact with one another instantly in the context of SharePoint so they can work more effectively on SharePoint sites, stored documents, and other content. Microsoft Office System
Instead of sending documents through endless rounds of review via e-mail, users can use integrated presence to contact colleagues to work on a document in real-time or approve changes right from Microsoft Excel, Microsoft Word, Microsoft PowerPoint, and more. Microsoft System Center
One of the key benefits of deploying Microsoft Unified Communications solutions is that you get enterprise voice and enterprise messaging capabilities integrated with your existing Microsoft infrastructure. That means IT administrators can use System Center to manage multiple Microsoft technologies using one centralized, familiar interface. Microsoft Active Directory
Having an integrated directory solution for the entire organization not only simplifies administration for IT professionals, it supports an efficient and unified end user experience. Lync Server 2010 works with the same Active Directory infrastructure that supports Exchange Server, network access, and other IT workloads, making it much easier to deploy and manage Unified Communications capabilities, and supporting a seamless communication and collaboration experience for users.
