Enterprise Voice - Microsoft Lync Server 2010 combines the telephony features of a traditional IP PBX with rich presence, instant messaging, and conferencing to improve communication and to lower costs. Users can access intuitive, powerful voice features—in the office, at home, or on the road—from phones, PCs, and desktop applications, while administrators benefit from a unified solution that is easy to deploy and manage. Microsoft Lync Server 2010 can replace or enhance your existing IP PBX system.

Instant Messaging & Presence - Microsoft Lync Server 2010 gives users real-time presence information and enhanced instant messaging (IM) to help them connect more efficiently and effectively.

Audio, Video, and Web Conferencing - Microsoft Lync Conferencing makes it easy for users to create, moderate, and join conferences with internal and external users. A rich user experience and a unified interface make it easy for workers to collaborate effectively and often even when time or distance prevents in-person meetings.

Group Chat - Group Chat allows users to have topic-based, multi-party discussions that persist over time, which allows efficient information sharing and discussions as a group.

Related Technologies - Most organisations do not think in terms of products but rather in terms of workloads and solutions. Microsoft designs its products to work well together as a platform that helps you address specific business needs rather than being just another product. Users and administrators get a familiar experience that helps them be more productive, while organisations save money by meeting multiple needs with an interoperable platform instead of buying and managing disparate solutions.
