How to switch between Skype for Business and Lync Client UI

with 8 comments

We are all going to get a new client for Lync and it is going to look a lot more like Skype. But here’s an interesting thing. With this new client, named “Skype for Business Client” now you or in many instances the administrator of your organization has the ability to change the UI of the client, either to;

  • Skype for Business Client
  • Lync 2013 Client

This new Dual User Experience mode that controls the Lync/Skype UI is managed via in-band settings. The client is by default configured to check for the Server Version of the environment and set up the looks. The below table lists what you may see by default.

Server Version Default Client UI
Skype for Business on-prem Skype for Business
Skype for Business Online Skype for Business
Lync Server 2013 Lync 2013
Lync Server 2010 Lync 2013


Although this is the case, the Lync/S4B administrator always have the option to change the UI via changing in-band policy settings that will manually override the default UI. There will be a Client Policy parameter that will determine the default UI for users within the organization. To enable the Skype UI and Lync 2013 UI the following commands can be run from the server end respectively.

Set-CSClientPolicy -EnableSkypeUI: true


Set-CSClientPolicy -EnableSkypeUI: false

So what happens from the users end? Head over to REGEDIT, Navigate to


and notice the value for EnableSkypeUI;

  • 00 00 00 01 – Skype for Business UI
  • 00 00 00 00 – Lync 2013 UI


However, there’s a catch. Based on the UI that you choose to have, the features may vary as show below.

Feature Skype UI Lync UI
First Run Experience Yes No
New Emoticons Yes Yes
Call and Video Monitor Yes No
Call via Work Yes No
RCC No Yes
Rate my call Yes Yes
Server side conversation history Yes Yes
Skype-Lync Video Interop Yes Yes





Update: Amanda Debler has written a nice piece of code that will help you to get the UI switched in seconds, you can grab the powershell script here.

Download Microsoft Office Professional Plus 2010 Trial for Free

with 5 comments

Great start-up on a Sunday evening everyone. Today I’m posting on  How you can get a Fully functional Microsoft Office Professional version for free from Microsoft it self. Microsoft is offering the 60 day trial of Office 2010 Pro. just in case you want to have a look, try out and make up your mind for sure if you want  get updated to the Office 2010 when it releases for retail users next month.  Of course if you have already running the Office 2007  you can easily get into the much more enhanced  and feature riched Office 2010 environment, and for previous Office version users, theres no doubt that you will love it and dump that old one.

So if you want to give it a spin it. head to the link given below. Remember that the license will expire in 60 days after you activate it.

If you feel that you need more time to play with it  you can use the Office 2010 beta for free too. As for this, you have the opportunity to have fun till October 2010. As for me, Iv been using the beta since it was released until yesterday and I didnt experience a single bug or any nasty errors.

Some Important info before you download :

  • Use Internet Explorer to download.
  • Read the instructions and additional information.
  • You should Sign In to the Technet Evaluation Center in order to download which requires a hotmail/live account.
  • A Microsoft(kind of) “Download Manager” will do the downloading process which can be paused or canceled at any time. The resuming will start from the point it stopped downloading.
  • Write down the key. The setup requires you to enter it at the starting of the Installation Process.

Download Microsoft Office Professional Plus 2010 RTM*
Download Microsoft Home and Office 2010 beta*

*RTM is the Final version where as beta is a testing release and therefore may contain bugs and errors.
