Release date: December 12, 2016

Features added

• Video-based screen sharing (VBSS) viewing is available for Microsoft 365. VBSS is technology that allows for a more efficient way of sharing content over the network as compared to RDP. Learn more.

• Single window mode for Lync Server 2013 users. Skype for Business on Mac already offers a great experience to manage multiple conversations in a single window. Now that experience is extended to Mac clients that connect to Lync Server 2013, which was not supported prior to 16.2. In addition, if server-side conversation history was previously disabled, single window was not available either. This is now addressed unless your organization has disabled EnableAutoIMArchive explicitly. Also, messages can be auto-accepted if the Mac client is active, and IMs can be shown as missed messages.

  • Single window:

    • Will not depend on SSCH. It will only depend on EnableIMAutoArchiving.

    • On when EnableIMAutoArchiving is enabled or not set.

    • Off when EnableIMAutoArchiving is disabled.

  • Auto-accept:

    • Skype for Business on Mac will always auto accept IM if it is most active endpoint.

    • If SSCH is enabled, it will be accepted by the server. The conversation will persist in Exchange and display in the conversation list.

    • If SSCH is disabled or not set (for example, in Lync Server 2013), the client will accept IM and display in the conversation window, but will not save it to the "Conversation History" folder in Exchange.

      • If EnableIMAutoArchiving is enabled or not set:

        • Skype for Business on Mac will show the conversation locally and it will not roam.

        • When user closes the conversation window or restarts the client, the conversation will reappear in the conversation list.

        • If user does a clean installation of Skype for Business on Mac or logs on from another computer, there will be no history of previous conversation.

      • If EnableIMAutoArchiving is disabled:

        • When user closes the conversation window or restarts the client, the conversation will not be persisted or show up in the conversation list.

• In audio calls, you can now add desktop sharing.

Improvements

• Changed the default notification type to banners. Users can change their settings on the Notification Center (Skype for Business > Preferences > Notifications).

• User experience during meetings and calls.

• Group management

• Client stability and other bug fixes.

  Single/tabbed window experience not available	By default, if your topology meets the following requirements, all conversations will be shown in a single/tabbed window.
