Summary: IT Professionals should review the support requirements for the Skype for Business Web App and Skype Meetings App while planning for Skype for Business Server. This article is not intended for the users of these apps.
Once you've implemented Skype for Business Server, your organization's users will presumably have the Skype for Business client installed as part of the deployment process.
Later on, those users may create meetings and invite users from outside the organization, and those meeting invitees may not have any version of the Skype for Business client. When those users click the URL for the meeting invite, the lack of a client will be detected and the invitee without a Skype for Business client will be asked to download and install a lightweight, meetings-only client so they can join the meeting.
Note
The Skype for Business Web App and Skype Meetings App are only available when trying to log in to a meeting without having Skype for Business. User help for these apps is at https://aka.ms/smahelp.
Note
You can't pre-install either the Skype for Business Web App or Skype Meetings App, but smart phone and tablet users may be able to install inexpensive mobile clients they can use to attend meetings.
By default, the server hosting the meeting will direct the user to download and install Skype for Business Web App to join the meeting. The Skype for Business Web App is stored on the Front End Server and gets sent to the meeting attendee.
For Skype for Business Server, Skype Meetings App (on Windows) and Skype for Business for Mac (on Mac) are available as replacements for Skype for Business Web App beginning with CU5, but providing the replacement apps requires the additional configuration described in Enable Skype Meetings App to replace Skype for Business Web App (Optional). If Skype Meetings App and Skype for Business for Mac are enabled, users will download the latest version of the apps from the Microsoft 365 or Office 365 Content Delivery Network (CDN) rather than from your Skype for Business server. For Skype for Business Server 2019, using Skype Meetings App and Skype for Business for Mac is the only option.
Skype Meetings App offers a simplified browser experience for downloading and installing the app and joining meetings, including one-click join for users of Internet Explorer. Skype Meetings App also has many improvements over the Skype for Business Web App for reliability and the meeting experience.
Note
As of Skype for Business Server 2015 CU5 or later, meetings held using Skype for Business Online will no longer send a clientless user the Skype for Business Web App, they will instead be sent Skype Meetings App (on Windows) or Skype for Business for Mac (on Mac). As of Skype for Business Server 2015 CU5 or later, if you Enable Skype Meetings App to replace Skype for Business Web App (Optional), clientless users will be sent Skype Meetings App or Skype for Business for Mac instead of Skype for Business Web App.

❶ The Skype for Business Web App browser plug-in requires a specific sharing plugin to use computer-based voice, video, sharing, and viewing of ongoing screen sharing and other features. A meeting attendee is given the option to install the sharing plug-in either when they join the meeting or when they initiate one of these features. On Windows 8, and Windows 8.1, the sharing plug-in can be installed only if you're running Internet Explorer 10 or Internet Explorer 11 for the desktop. These features are not available with non-desktop versions of Internet Explorer 10 and 11. Note that Firefox and Safari version 12.0 and later is no longer supported.
❷ On supported Windows 7, Windows Server 2008 R2, and Macintosh operating systems, all features are available including computer-based voice, video, application viewing, application sharing, desktop viewing, and desktop sharing. To use these features, you must install a plug-in when prompted. Note that Mac OS X version 10.7 is no longer supported. Also note the web app will not install on OS X 10.15 or later. We recommend using the latest version of Skype for Business for Mac which supports anonymous join scenarios moving forward.
❸ Accessing the Web App from Chrome on Windows will launch a small program which loads the Web App in an embedded Internet Explorer frame. This program requires one of the supported versions of Internet Explorer be installed for the Web App to load properly.
Note
Microsoft 365 and Office 365 users can use Internet Explorer 10 or later with Skype for Business.
Skype Meetings App
Skype Meetings App runs as an app on computers using Windows 10, Windows 8.1, Windows 8, Windows 7, with 32- and 64-bit Internet Explorer 11 or later installed.
For any other dependencies, refer to Supported platforms for Skype Meetings App
Skype for Business for Mac
Skype for Business for Mac runs on computers using macOS version 10.8 or later.
Hardware requirements
Computer hardware requirements are determined by the operating system and browser. Voice and telephony features require a microphone and speakers, headset with microphone, or equivalent device compatible with the computer. Video features require a video device compatible with the computer. For detailed information about video hardware support and expected video quality, see Skype for Business client video resolutions.
Network requirements
If a user of Skype for Business Web App or Skype Meetings App experiences meeting connection issues, chances are their organization's network infrastructure is not configured to support Office 365 as described in Office 365 URLs and IP address ranges. This is the case whether the meeting was created by a user of Skype for Business Online or Skype for Business Server.
If the user is on a network not configured as described, many app features may or may not work and they may not be able to connect to the meeting at all.
Supported Meetings features
This table compares the Meetings features available to users of the Skype for Business client, Skype for Business Web App, Skype Meetings App, and Lync Web App. Lync Web App is listed for feature comparison purposes: a user would only be downloading and using Lync Web App if the meeting was hosted on a Lync 2013 server.
