Microsoft Lync Web App was introduced with Lync Server 2010. Lync Web App is a browser-based version of Microsoft Lync 2010, which allows users who don’t have Lync 2010 or Lync 2010 Attendee installed on their computer to participate in online meetings—even if they don’t have a Lync 2010 account. Lync Web App for Lync 2013 expands the capabilities of Lync Web App for Lync 2010. This article outlines the new features and how they compare with the earlier version.

Before we consider the new Lync Web App, let’s review the features of the Lync 2010 version.
When compared to the full Lync 2010 client, Lync Web App for Lync 2010 has a few limitations. The biggest limitation is the inability to use computer audio and video, and to upload PowerPoint presentations in meetings. Additional limitations for Lync Web App for Lync 2010 are as follows:
NOTE The only requirement to run Lync Web App is to install the Microsoft Silverlight browser plug-in. Silverlight installs a dedicated plugin for desktop and app sharing. Lync Web App is supported on both Windows and Macintosh operating systems.
The following changes have been made to Lync Web App for Lync 2013.
Note: Because Lync Web App for Lync Server 2013 is full-featured, there is no longer a need for a Lync Attendee client.
When a user clicks a Lync Meeting URL, but doesn’t have the Lync 2013 desktop client installed, the user is presented with the option to join the meeting using the latest version of Lync Web App.
The new streamlined interface for Lync Web App is focused on helping the user join the meeting as a guest, as follows:
On the Lync Server 2013 Front End (for single server installations), Front End pool, and Director roles, there are two websites—internal and external. When a user accesses the Lync Web App meeting from inside the corporate network, the Lync Web App meeting is serviced from the internal website; otherwise, it is serviced from the external website. This is also true in the case of a split-DNS server. In case of a hairpin DNS—internal requests are referred by internal DNS records to the external website. The request exits the internal network and immediately turns, or hairpins, to the external entry on the reverse proxy. Lync Web App is always serviced from the external website, regardless of whether the user is inside or outside the corporate network.
Lync Web App for Lync 2013 supports the following authentication mechanism for an online and on-premises user.
For online users, Lync Web App supports OrgID authentication, as does the rest of the Microsoft Office applications. An organization can have Office 365 accounts for a few users who get direct access. Or, an organization can turn on Active Directory Federation Services (AD FS) authentication for users who are Active Directory-based and do not have an Office 365 account.
For on-premises users, Lync Web App supports the following authentication methods:
Guest login is supported in both online and on-premise modes.
Lync Web App for Lync 2013 supports the following scenarios:
To use Lync Web App, you must have one of the supported operating system and browser combinations listed in the TechNet Library topic, Lync Web App Supported Platforms.
Here are some troubleshooting tips:
For meeting join-related issue
For PowerPoint presentation-related issues
For desktop sharing-related issue
For Audio/video-related issues
For instant messaging & presence (SIP )-related issues
As of January 2013, there is a potential issue with clients using Lync 2010 and Lync Web App for Lync 2013. Lync 2010 clients might not be able to view PowerPoint content uploaded from a Lync Web App for Lync 2013 client. A fix will be available sometime in the future for the Lync 2010 client to correct this behavior.
The new Lync Web App for Lync 2013 client is a step forward in the evolution of the Lync client. The streamlined user interface makes it easy for users to seamlessly join a meeting. Plus, the new Lync Web App now delivers end users with a complete meeting experience, without the need for a client application installation.
