Skype for Business Client Testing in Lync 2013 on PremiseEnvironment

Microsoft has released Skype for Business Client.  Lync 2013 client will become Skype for Business after April 14, 2015 as part of regular Office monthly updates if performed by the organizations.

This Skype for business client will be working on  Lync 2010 & 2013 on premise registrars servers and Lync Online . But specific server builds are required on Lync Server 2013 and Lync Server 2010 onpremise in order to set client policies

Below are the prerequisites for Lync 2010 & 2013 OnPremise Servers

Minimum server Build for Lync 2013 – Deploy server build 5.0.8308.857 (December, 2014) or later.

Minimum server Build for Lync 2010 – Deploy server build 4.0.7577.710 (February, 2015) or later.

If you have the above build version on your Lync 2013 server you can go ahead and start testing .

But before setting this policy to all the users it is better that if we test this new client in few of the users and then we can deploy them to rest of the users.

Inorder to to that follow the below steps

First run Get-CsClientPolicy to check how many policies you have .



If we have any test client policy already you can try with the policy. In most of the cases we might be having only default global policy. It is better not to  play around with this since it will affect all the users if at all there is any issues.

So its better to create a new Client Policy to test this client on the few user accounts.

Run the below command to create a test client policy

New-CsClientPolicy -Identity SkypeforBusiness -EnableSkypeUI $True



Run the below command to grant the client policy to the  users for testing this client functionality.


Grant-CsClientPolicy  -Identity username -PolicyName SkypeForBusiness




Once the above is done you can download the Skype for Business client for the test users and start testing the client functionality.

Configuring federation , external access and limitations in Lync 2013

Configuring external access in lync 2013 is one of the challenging part for the administrators.

In this article we will see the options to configure external access and few limitations that we have on them.

In order to perform that open Lync Server Control Panel  and click on federation and external access as shown below.




Choose the type of external access policy that you would like to have configured


Note : By default there will be global policy and its not enabled until we enable them.This policy is created while you deploy edge servers.

In the access edge configuration we have the below settings as shown




Public IM – for Outlook,Hotmail and public messenger that are supported refer more on technet for this part.

Enable Anonymous – For users joining the meeting by providing the link

The below option SIP Federated Providers that are hosted providers running Microsoft Office 365, Microsoft Lync Online and Microsoft Lync Online 2010




We have an option to specify allowed domain as well as blocked domain.



Below option is for SIP federated providers.



Below is the option for the SIP federated providers



Below is the option for specifying XMPP federated partners



Can we control this federation access services to few users and give full access to rest of the users ?

Lets take an example where a company wants to federate with us but we don’t want them to have A/V access to all of their users but need to enable full federation services IM,Presence,A/V only for few users.

Can we achieve this with the policy ?

The answer is no . Because the policies are not defined that granular.We can block outside AV access altogether through firewall or stopping the A/V edge service but making this change will stop a real user from our organization from using A/V when connected remotely.

So the final conclusion is that the current policies cannot be configured as of now to control federation in few services A/V for few users and to allow for rest of the users but still this can be achieved with some third party products.
