Lync (formerly known as Office Communications Server) is Microsoft's next-generation communications suite that brings together IM, voice and video through Lync Online and Lync Server on premise. Lync brings together real-time presence information of the users with instant messaging, voice communication and video conferencing, and it integrates with the MS Outlook and MS Office applications that can further increase efficiencies in your organization. Lync clients also can be used on mobile devices for increased mobility as well as through the web application where even a third party could join an internal web conference through Lync meetings.

Lync 2013 works in 1080p HD resolution for video conferencing that enables participants to get a more realistic experience through sharp, clear visuals. If you are a user of Windows Phone, iOS, or Android, Microsoft has developed a Lync mobile app which enables you to communicate using Lync when the move. Through Lync Mobile apps, users can call, instant message, or join a Lync Meeting from virtually any location.

Microsoft has also introduced a Web app for Lync 2013 through which users can log into Lync and join a meeting from almost any current browser. This is a great feature for users who do not have immediate access to their laptops or desktops while at work or on the move; all they need is a web enabled computer running a current browser.

In the course of business you are bound to come across partners, vendors, and customers who do not use Lync. To accommodate non-Lync users, Lync 2013 encompasses integration with Skype providing presence (status), IM, and voice.

Lync is now part of Microsoft's premier cloud offering, Microsoft Office 365, which bundles Exchange, SharePoint, Lync and Office at an affordable monthly subscription cost.
