Important Notes

4487824 Updated job title isn’t displayed in the Skype for Business for Mac or mobile client in Skype for Business Server 2015 | In a Microsoft Skype for Business Server 2015 environment, you update the job title for a user in Active Directory. When the user uses the Skype for Business for Mac or mobile client to join a meeting, the old job title is still shown for the user in the roster of the meeting. However, the contact card shows the correct job title.
This issue occurs because the changes aren’t pushed to the Skype for Business server database. |
4487825 Support for sending custom policies to UCWA clients in Skype for Business Server 2015 | After you apply this update, Microsoft Skype for Business Server 2015 will provide custom policies to the UCWA client (such as the Skype for Business for Mac or mobile client). The custom policies are configured through the New-CsClientPolicyEntry cmdlet. This enables UCWA clients to support custom policies like Skype for Business App for Windows. |
4487826 UCWA client drops an incoming call on SBAs from a federated user in Skype for Business Server 2015 | Consider the following scenario:
In this scenario, you can accept the incoming call. However, the call is a one-way audio from the UCWA client to the federated user, and no audio comes back. After about 15 seconds, the call drops. In addition, the outgoing call isn’t affected.

4487827 Simultaneous ring not working after you install Skype for Business Server 2015 November 2016 Cumulative Update | After you install the Microsoft Skype for Business Server 2015 CU4 (November 2016 Cumulative Update), the simultaneously ring feature only works intermittently in the Skype for Business client. |
4487828 Can’t automatically sign in to Skype for Business for Mac after EnableMobility is set to false in Skype for Business Server 2015 | You set the EnableMobility parameter to false in order not to let users use Skype for Business on their mobile phones in Microsoft Skype for Business Server 2015. In this scenario, the users can’t sign in to the Skype for Business for Mac client automatically after switching a network or hibernating the computer. In addition, the Skype for Business for Mac client displays “Restoring the server connection…” but does not connect, and displays the sign-in screen. |
4487819 Intranet URI is still filtered even if IgnoreLocal is set to True in Set-CsImFilterConfiguration in Skype for Business Server 2015 | In Microsoft Skype for Business Server 2015, you define the IgnoreLocal parameter to True in the Set-CsImFilterConfiguration cmdlet to bypass the instant message (IM) filtering on local intranet Uniform Resource Identifiers (URIs) in IMs. However, the IM that contains any URL such as http://contoso.com/site (the contoso.com is the local domain) is still filtered. |
4487820 Audio conference invitations are sent to delegates of your delegates if you set up simultaneous ring to delegates in Skype for Business Server 2015 | Consider the following scenario in a Microsoft Skype for Business Server 2015 environment:
In this scenario, both user A and user B receive the audio conference invitation. If you have many delegates and your delegates also have delegates, the audio conference invitation will be sent to all the delegates due to simultaneous ring. This can cause the Skype for Business Server Front-End service (RTCSrv.exe) to exhaust a lot of memory. |

4487818 Skype for Business UCWA client can’t be distinguished on CDR report if connection is internal or external | In a Microsoft Skype for Business Server 2015 environment, you use the Skype for Business on Mac or mobile client that’s in an external network to start a call with a Skype for Business client user. You may find that the value of Is From user internal or Is To user internal (depending on whether the UCWA user is the caller or callee) always shows Yes on the Call detail recording (CDR) report. It’s expected that the clients should be flagged correctly as external or internal on this report. |
