Join a Meeting Using Lync Web App

Watch a Lync Web App video!

Lync Web App is almost identical to the meeting experience offered by the full version of Lync. If you received a Meeting Invitation for a Lync Meeting and you are a student, vendor, contractor, guest of UH, or simply don't have Lync on your computer - download and install Lync Web App to experience a Lync Meeting in a web browser. To experience full audio and video in a meeting, use Lync Attendee.


Lync Web App is a browser-based version of Lync that contains all of the Lync in-meeting features except for desktop sharing, computer audio and video. A phone must be used for audio. Microsoft Silverlight is required. If Silverlight is not on your computer, it will download and install during the Lync Web App installation.

Features of the Lync Web App include:

  • Dial-in and dial-out (“Call me”) audio conferencing
  • Detailed meeting roster
  • Multi-party instant messaging (IM)
  • Desktop and program sharing, including giving control to participants (program sharing not available for Macintosh)
  • Collaboration features, including a whiteboard, poll and file sharing (whiteboard and poll not available for Macintosh)
Required Plug-ins
Lync Web App requires Microsoft Silverlight 4.0 (or later) browser plug-in. If Silverlight is not installed, you are prompted for installation. Desktop and program sharing features require a Lync Web App plug-in. The first time you initiate a sharing session, a prompt appears to download the required sharing plug-in.

Before your first meeting, run the meeting readiness program to determine if you have the required plug-ins installed. In a Meeting Invitation, click First Online Meeting and follow the instructions. If necessary, you will be prompted to download and install all missing plug-ins in preparation for your first online meeting.
