Lync Server 2013 - The *NEW* Lync Web App

Lync Server 2013 - The *NEW* Lync Web App

In the tough economic times we find ourselves in today, remote working and the ability to have rich online meetings are becoming more and more important. One of my colleagues B. Roop Sankar (Unified Communications PFE) has written the below article, which highlights some of the new additions and improvements to the Lync Web App. Hopefully this information can help you reduce travel costs and increase your productivity!

Conferencing capabilities such as Web Conferencing (sharing PowerPoint etc) and Audio/Video Conferencing have always been available in Lync Server 2010 and its previous versions. However the conferencing experience was different based on who was joining the conference. This was especially noticeable when users from outside the company (anonymous users *) were invited to join a Lync Meeting and didn’t have the Lync client installed.

These anonymous users would join the meeting using a web browser which is called the Lync Web App. The features available to users via Lync Web App are;

· Dial-in and dial-out (“Call me”) audio conferencing.

· Detailed meeting roster.

· Multiparty instant messaging (IM).

· Desktop and program sharing, including giving control to participants (available for Windows only; not available for Macintosh).

· Collaboration features, including whiteboards, polls, file sharing, and navigating PowerPoint presentations uploaded by others.

Though this was feature rich it was still did not encompass a seamless collaboration experience. Some of the limitations are;

· Silverlight had to be installed (which required Administrator privileges).

· No IP Audio and IP Video.

· Cannot upload Microsoft PowerPoint presentations.

· Dial-in and Dial-out was generally disabled to prevent call fraud.

· Desktop and program sharing only available for Windows.

· *All the above could be provided to the end user using the Lync Attendee client. However looking at the size of the install (approx. 61.1MB), I would let you decide if this would be a good user experience.

The *NEW* Lync Web App provides all of the above and much much more!!!

Given below is a table that highlights the new features that are available.


Voice & Video

Collaboration over Content

Meeting Management

· Join as guest with a single click

· Quick plug-in installation – user-level install, not dependent on Silverlight

· Audio over IP

· Video over IP

· Multi-participant video

· Speaker indication

· Speaker video over content

· Dial out, dial in

· Desktop sharing

· Specific application sharing

· Give and take control of desktop

· Real-time note-taking

· Upload PPT, share and annotate in real time

· Whiteboard

· Poll

· Participant list

· Manage participants

· Schedule meeting

All these features are available in all of the major Web Browsers (IE, Safari, Chrome etc) and this link will provide you further information on the supported operating system and browser combinations.

Since they say that a picture can say a thousand words, I’ll stop writing and show you all the new features.

Multi-Factor Authentication for Lync Web App

*Anonymous Users - Anonymous users are users who do not have a user account in your organization's Active Directory Domain Services (AD DS) or in a supported federated domain, but can be invited to participate remotely in an on-premises conference.

  • >The first time users initiate a sharing session, they will be prompted to download the required sharing plug-in.

    >On supported Windows XP, Windows Vista, and Windows Server 2008 operating systems, computer-based voice and video are not available. Application viewing and application sharing are available.

    You missed this in your exiting story. It is so funny to have binary browser plugin installed in the era of HTML5 and Flash webinars. Installer also requres administrative rights, to generate even more stupid work for IT. Excelent!

  • Hi Guys as per your table can  domain joined user can log on from a PC with no Lync2013 client and schedule a meeting ?

  • On the web application conference I see the Login and Password and below I see guest.  Can the application be set to just show guest  anonymous user only.  Our customers do not want to show the Login and password to an outside party.
