Requirements for Skype for Business Meetings
Full Skype for Business (UNC Affiliates Only – requires an ONYEN)
When attending a Skype meeting, UNC participants may opt to use the Skype for Business software which is included with Microsoft Office 2013 for Windows or newer. Additionally, the 2010 version of Microsoft Lync is still compatible with Skype for Business, and is available from Microsoft ( https://www.microsoft.com/en-us/download/details.aspx?id=36517 ), though the features and interface are slightly different with the 2010 version.
