Server update

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.

Outlook integration

Requirements for Skype for Business and Outlook integration on Mac:

  • Mac Outlook version 15.28 or later is required.

  • Skype for Business must be running.

  • Same user account needs to be signed into Outlook and Skype for Business.

Troubleshooting Outlook integration in case Contacts don’t show presence, online meetings fail to schedule, or there is no dial-in information in meeting invitation:

  1. Ensure the user account is the same in Outlook and Skype for Business.

  2. Restart Outlook.

  3. Reinstall Skype for Business on Mac.

  4. Perform clean uninstall of Lync 2011. See How to Perform a Clean Uninstall of Lync for Mac 2011 for more information.

  5. Ensure Skype for Business is running and signed in.

Can’t see users’ Skype for Business presence in Outlook 2016 for Mac

If you have Lync for Mac 2011 installed on the same Mac device, Lync for Mac might have changed the configuration. Recommend that you reinstall Skype for Business on Mac.

Can't search Skype directory

Skype for Business on Mac users can't search the Skype directory, although you've enabled this functionality for your organization.

Side-by-side installation

Side-by-side installation of Skype for Business and Lync is not supported on Mac. We recommend that you perform a clean uninstall of Lync for Mac 2011 prior to installing Skype for Business.

Cannot sign in to Skype for Business

Some Lync profiles might be different from Skype for Business on Mac profiles and can cause a discrepancy. See How to Perform a Clean Uninstall of Lync for Mac 2011 for more information.

Mobility Policy required

With the release of Skype for Business Server 2015 CU4 and Lync Server 2013 CU8 HF1, we will support Skype for Business on Mac as a desktop application. This means that having a mobility policy assigned to Mac users will not be required. Until these server updates, Mobility enablement on the server side is required.

Meeting invitations only display a single dial-in number

Fix: Update to Outlook 2016 for Mac build 15.32 or later.

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.

Adding a distribution group that has more than 100 contacts will result to 100 contacts only

Workaround: To view the full member list of distribution group, use Outlook to expand the group.

Search contacts limitation

There is a known limitation with Mac search where it will not show personal Outlook contacts, federated contacts, and Skype consumer contacts; it can only show contacts in the local Active Directory.

Desktop viewing in Skype for Business on Windows client

While in a peer-to-peer session between a Windows Skype for Business client and a Mac Skype for Business client, and sharing is started by the Mac Skype for Business client, the Windows Skype for Business client will not be able to see the Mac user's desktop. Desktop viewing is currently not supported in this Skype for Business scenario for Windows on-premises users.

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

PSTN conference info missing in Outlook for Mac

PSTN conference info is missing when scheduling an online meeting in Outlook for Mac.

Workaround: To fix this issue, you have to delete an Outlook setting:

  1. Exit Outlook for Mac.

  2. Open Terminal.

  3. Type: defaults delete com.microsoft.Outlook OnlineMeeting

  4. Start Outlook for Mac.

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 only supported on Skype for Business Server 2015 with UCS disabled

Users on Skype for Business Server 2015 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 (UCS) for Exchange. If the users are hosted on Lync Server 2013, Contact Management is not supported. Users can make changes to their contacts list in Outlook. Delegate Management can be done by the Lync or Skype for Business administrator using the SEFAUtil administrative tool.

Skype for Business Server 2015 with UCS disabled is the only currently supported Contact Management.

Enhanced 911 (E-911) support

Support for E-911 emergency calls made from Skype for Business on Mac has the following requirements for on-premises servers:

  • Skype for Business on Mac version 16.11 or later.

  • Skype for Business Server 2015, December 2017 update or Lync Server 2013, November 2016 update (CU8 HF1).

  • Enable911 in CsPlatformServiceSettings must be true.

  • West Safety Services customers: Emergency Gateway Version 5.4.

  • EnhancedEmergencyServicesEnabled property of the user’s location policy is enabled. (Note: it is not sufficient to enable EnhancedEmergencyServicesEnabled on the location policy applied to the network site of the subnet to which the user is connected.)

Instant messaging (IM) notification for emergency calls not sent to a distribution list

When the notification URI in the location policy is specified as a distribution list, the IM notification is not sent from Skype for Business on Mac. 

Workaround: Specify one or more SIP URIs as the notification URI.

In Outlook, cannot join a meeting from a non-federated organization

Users cannot join a meeting from another organization that isn’t federated with your organization when users click the join links in Outlook.

Workaround: Join the meeting from the Meetings tab inside the app (version 16.11.149 and later).

Conference access settings do not default to values defined by policy when scheduling a meeting from Outlook on Mac

The default values defined by the administrator might not be honored when scheduling an online meeting in Outlook, including whether to make a meeting public or private, who can be a presenter, and whether to play entry and exit announcements.

Workaround: When scheduling a meeting, select Set Access Permissions, set the desired values, and then select Remember settings.

Large PowerPoint files cannot be shared in a meeting

PowerPoint files that are larger than 30 MB can't be shared in a meeting from Skype for Business on Mac.

Workaround: Open the PowerPoint file on the computer and share the screen in the meeting.
