Description
Lync 2013 provides a single, unified client for real-time communications, including voice and video calls, Lync Meetings, presence, instant messaging, and persistent chat. These features require the ability to log into the service with a username and password. The Lync client could potentially be configured to store user passwords locally which would allow it to be susceptible to compromise and to be used maliciously.
