Server update

E-911 support requires Skype for Business Server 2015 CU4 (build 9319.272 or later) or Lync Server 2013 CU8 HF2.

Important: Users will not be able to dial 911 until the CU4 server update is applied.

Without Skype for Business Server 2015 CU4 (build 9319.272 or later) or Lync Server 2013 CU8 HF1 (build 8309.973 or later), Skype for Business on Mac requires Mobility enablement on the server side. After updating to builds 9317.272 or 8309.973 or later, Mobility enablement will no longer be required.

You can download these updates at Updates for Skype for Business Server 2015 and Updates for Lync Server 2013.

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. However, there are cases when the client can’t detect if server-side conversation history is enabled and it will not default to single window view. This can be remedied by updating settings in Preferences.

Requirements for single/tabbed window experience:

  • Skype for Business Online or Skype for Business Server 2015

  • Server-side conversation history enabled.

Troubleshooting if single window mode is not available, check the following:

  • Preferences > General > Show conversation in separate windows is unchecked.

Workaround: Users can join a conference call or use "Meet Now."

Skype for Business on Mac fails to sign-in

(Skype for Business Server Online, Exchange Server Online, Identity managed on-premises with ADFS 3.0 and WIA authentication enabled for wiasupporteduseragents-Mozilla/5.0)

Workaround:

  1. Remove “Mozilla/5.0” from the WIASupportedUserAgents parameter in AdfsProperties. Essentially, you will need to:

    1. Run Get-AdfsProperties | select wiasupporteduseragents and get the output.

    2. Then remove _only_ “Mozilla/5.0” from the output.

    3. Then run Set-AdfsProperties -WIASupportedUserAgents with the output from step b.

  2. Revert back to using Lync for Mac 2011.

Note: Skype for Business on Mac gets represented by the underlying ADAL library as user agent Mozilla/5.0 (no option to set it from the app), and Windows Integrated Authentication is generally used only for Windows clients and therefore not supported by ADAL library on Mac.

Contact Management, including Delegate Management, is not supported on Lync Server 2013 if Unified Contact Store is enabled

Users on Lync Server 2013 cannot modify their contacts list in Skype for Business if a user account is enabled by the Skype for Business administrator for the Unified Contact Store for Exchange. Users can make changes to their contacts list in Outlook.
