Microsoft’s Troubleshooting Guide

Applies To: Lync Web App for Lync Online, Lync Web App

The Lync Web App plug-in is required for audio, video, and screen sharing during a Skype for Business (Lync) Meeting. If you’re having trouble with plug-in, try these suggestions first:

  1. Make sure your computer operating system and web browser are on the list of supported platforms.
  2. Go to Control Panel > Programs and features and, if required, uninstall existing versions of the plug in.
  3. Open an InPrivate browsing session in Internet Explorer and try joining the meeting again. If that succeeds, consider clearing your browser cache to remove obsolete credentials that might be interfering with sign-in.

If you still can’t install the plug-in, review this list of issues and errors.
