This issue appears to be local to this pc, as it happens to the end user and also to myself logged onto the same pc, but it does not happen to us on other machines. Un/reinstall of Office 365 had no effect. Un/reinstall of CUCIL had no effect. All video and audio drivers are up to date. We have not yet pushed out Skype for Business 2015 to the company. Audio and video in a regular Lync conversation work. The issue appears when she joins a Lync meeting via a link in an email or her Outlook client's calendar event. The link kicks off the local Lync client and attempts to join the meeting, and if she chooses anything BUT "Lync Full Experience" it works. Windows 7, 64 bit machine.
