Changes in User Interface for Lync 2013/Skype for Business Client

Changes in User Interface for Lync 2013/Skype for Business Client

A big step for the transition from Lync to Skype for Business (SfB) has been made. Along with the client update pushed out on April 14th comes the new Skype for Business user interface.

Continue using the Lync 2013 user interface

If you are using a Lync Server 2010/2013 the default user interface will be Lync. If the update is installed and you start your Lync/Skype for Business Client for the first time, you client will start in “Skype for Business Mode”.


After a successfull login the user is prompted that Skype for Business is available, but your admin either would like you to use Lync or it is not supported by your server.


The user then restarts the client and can use Lync UI from then on (as long as the configuration is not changed) without the prompt.

Disable SfB UI without showing changes to the users

If you want to start directly with Lync UI after the update set the following registry key:

location [HKEY_CURRENT_USER\Software\Microsoft\Office\Lync]
value type Binary
value name EnableSkypeUI
value data 00 00 00 00

Enable Skype for Business UI for Lync Server

You can enable Skype for Business UI using Lync client policy and the following command (in this case I’m using the global policy):

Set-CsClientPolicy -Identity Global -EnableSkypeUI $true

In order to be able to do the configuration above, you have to patch your Lync Server to the following level:

Lync Server 2010 4.0.7577.710 – Febuary 2015 – CU15
Lync Server 2013 5.0.8308.857 – December 2014 – CU9

Changes that apply with the April update regardless of the UI you are using

Regardless whether you are using Skype for Business UI or Lync UI after installing the April update, you will notice some changes.

The Skype for Business icon is used as the overall client icon.

SfB_4 – taskbar icon


In Outlook you will schedule a “New Skype Meeting” instead of  a “New Lync Meeting”.


The new Skype for Business sounds will be used as overall sounds for the client.
