Lync Online connects people everywhere, on devices running Windows 8 and other operating systems, as part of their everyday productivity experience. Lync provides a consistent, single client experience for presence, instant messaging, voice, video and a great meeting experience. Lync enables instant messaging (IM) and voice calling with the hundreds of millions of people around the world who use Skype.
Organizations can purchase Lync Online as a standalone service from Microsoft Office 365 or as part of an Office 365 for enterprises suite that includes Lync Online, Microsoft Exchange Online, Microsoft SharePoint Online, Microsoft Office Professional Plus, and Microsoft Office Online. Organizations that subscribe to Lync Online retain control over the collaboration services they offer to users, but they do not have the operational burden of on-premises server software. With the Lync Online multi-tenant hosted plans, Lync is hosted on multi-tenant servers that support multiple customers simultaneously. These servers are housed in Microsoft data centers and are accessible to users on a wide range of devices from inside a corporate network or over the Internet.
