By popular request here is an updated article, similar to that of the living Updating Lync 2013 article, which will track the various Skype for Business client and server updates. Note that as with the previous article the various mobile clients are omitted mainly due to their update frequency and little value the historical data really provides.
Server Updates
Download
As Microsoft only provides the latest releases for the server components then the following two links are always updated with the most recent information and can be used as a definitive source of the latest server updates.
- Skype for Business downloads and updates – Office TechCenter listing of all official updates
- Updates for Skype for Business Server 2015 – Comprehensive KB article listing for all server components
- Skype for Business Server 2015 Cumulative Update KB3061064 – Direct link to Microsoft Download page for server packages
Unlike Lync Server 2013 which provided both individual component package downloads and the entire installer package only the complete installer package (SkypeServerupdateInsaller.exe) is available for Skype for Business Server 2015.
Installation
Just as with applying updates to Lync servers the same basic guidance exists for Skype for Business servers:
- Download and run the the SkypeServerUpdateInstaller shown above.
- Start inside-out and work from Front End servers toward Edge servers.
- Do not forget to update and verify the backend SQL database for each Enterprise Edition pool that is patched
Component History
For occasions when working with the individual packages is desired then the following table covers each cumulative update release with links to the original Knowledge Base articles for each new component.
This matrix provides a visual aid to when and how often some of the various Lync components are updated as cumulative releases will typically not refresh every single server component. The official package version numbers will always be in the format of 5.0.8308.xxx but the 5.0 has been truncated fro the following table for spacing purposes.
| Version 6.0.xxxx.xx |

Client Updates
The client versions listed in this article are only applicable for the Windows Installer (MSI) packages which are still made available by Microsoft to Volume License customers . The newer Click to Run (C2R) distribution model (explained in more detail here) is now the favored method of providing Office software updates and will not be recorded in this article. As these updates are released much more frequently it would be a dauntless task to keep up to date, as well as a bit pointless as environments leveraging C2R are not really concerned with understanding and managing periodic updates
Skype for Business 2016 Windows Client
The following table lists major 16.x client version update packages with links directly to the download pages for the clients for each processing architecture (32-bit versus 64-bit). Be aware that Microsoft recommends using the 32-bit version software in most cases, even on 64-bit platform.

Skype for Business 2015 Windows Client Updates
A current listing of Skype for Business 2015 (15.x) client updates is still maintained in the Updating Lync 2013 article.
Jeff, my version of Skype for Business 2016 is 16.0.6828.1016 64-bit. When I view my Configuration Information, the MAPI Information shows “MAPI Unavailable”. This problem has been document in Microsoft Article ID: 3147130 (https://support.microsoft.com/en-us/kb/3147130).
Are you aware of any to automate the deployment of the workaround or if Microsoft is planning on releasing a proper fix? Thanks.
No, I’m not aware of this.
hmmmz i’m looking for the same, not able the get the legacy DN automated, need to deploy it for 1000+ users….
Hi Jeff Schertz!
My name is Sergio and I have a question for you. (Sorry about my English)
I have created an UCMA (C#) Application in order to make a Chat Support between Clients (UCMA App) and Agents (Skype for Business 2015). Trusted Application Pool, Servers, and Config. is all good establish.
At the moment, i have a Desktop Application and I can create different Chat Windows with the same UserEndpoint in order to chatting at the same time with an differents Available Agents (Skype4B) but always 1-to-1.
The question is, if I can with the same UserEndpoint create 2 different Chat Window (for example, Client1 and Client2) to chatting with the same Skype4B Contact and received the messeges for the Clients in a different Skype conversation (different window or lash) or I need to have 2 different UserEndpoints???
Thank you in Advance.
Sergio.
Sorry, as I’m not a developer I can’t really say if that is possible. Maybe someone else can provide some assistance.
Hi Jeff! Are you aware of any known or unknown issue patching the 2016 “basic” branch?
If you look over Technet forum title: Skype for Business 2016 Basic Client Patches
https://social.technet.microsoft.com/Forums/en-US/8e5c91ae-270f-43d6-9722-a173f6c2ef03/skype-for-business-2016-basic-client-patches?forum=sfbfr
seem lot of people are stuck and unable to apply these updates to sfb 2016 basic, and I experience the same.
I haven’t used the Basic client in some time so not sure why that happens.
Hmm, well.. okay then. I hope this comment raises some interest in this topic, and will lead to a solution in the near future.
There is now a solution!
Install Sfb 2016 basic v2016.04 fom here: https://www.microsoft.com/en-us/download/details.aspx?id=49440
(if you have RTM Sfb basic, uninistall it first)
Then you can install Sfb2016 CU 2016.06 from here: https://support.microsoft.com/en-us/kb/3115268
And this time it will apply the update instead of just throwing some nonsense error message. And voila, you have ABS in Sfb2016 basic + all the fixes that was solved in the big Sfb2016 clients months ago. Enjoy!
Hey Jeff
Great summary, thanks for the cross link re C2R
cheers
Tom

Yes they are cumulative, going back to a certain point. You can see in the table where any older version prerequisites exist. You don’t have to keep installing all of those packages.
Hello Jeff,
i downloaded Skype for Business Server 2015 Cumulative Update KB3061064.
I followed instructions in https://support.microsoft.com/en-us/help/3061064/updates-for-skype-for-business-server-2015.
when i Run the Cumulative Server Update Installer, it gives me “SUCCESS: Found the main process.” and stop. do you have an idea what should I do?
did you ever find out the cause of “SUCCESS: Found the main process.” when running the SKype CU??
Just in case anyone comes looking for the answer to this here, that message is telling you that the process is already running and it’s not going to spawn another, so you have to kill it in taskman before you can run it again.. 🙂
Jeff,
What about the servers formerly know as WAC for Skype 2015? I cant find alot on updates for them
I don’t think the older version is getting much in the way of updates these days. The updated version is called Office Online Server: https://blogs.office.com/2016/05/04/office-online-server-now-available/
Check this site:
http://www.toddklindt.com/blog/Lists/Posts/Post.aspx?ID=346#OWA
There are monthly updates for OWA2013 server actually, so its not mandatory to use Office Online Server , as OWA2013 is still supported.
Hi Jeff, what about CU5 and Windows 2016 server official support?
Thanks for the great work
Hi Jeff. We have been awaiting release of Skype for Business Server CU5, as this was supposed to provide support for running SfB 2015 on Windows Server 2016. The “May 2017” cumulative update was just released, however Microsoft has not updated support guidance for Skype for Business Server 2015: https://technet.microsoft.com/en-us/library/dn951388.aspx#OS
Could you please confirm whether Microsoft now supports SfB server 2015 on Windows Server 2016? Thanks.
Can you download the old updates / components from 2/17 separately ? It looks like you can only download the most recent updates.
Correct, Microsoft replaces older versions with the latest.
why no recent updates for the newest CUs to SfB server?
I’ve been busy 🙂 Just updated the page with the latest server and client versions.
I’ve observed that even if you update a client machine using a cumulative update package, such as KB4011040, it might not affect the Skype client at all.
I did a test:
* Create a VM running Windows Server 2012 R2 (this was the only OS I could provision without having to manually install it)
* Do NOT install ANY Office software.
* Install the RTM Skype for Business client. The client reports itself as 16.0.4266.1001.
* Install KB4011040 and reboot
* The client now STILL reports itself as 16.0.4266.1001
* Check for updates (MS Update) and install all Office updates, even if they are for non Skype products. There are about 50 updates, and they are for Excel, Outlook, Word, Publisher, Visio etc.
* The client now reports itself as 16.0.4546.1000.
So there are a lot of dependencies that Microsoft do not inform you about directly (the KB pages do not list any other components as prerequisites).
And why don’t MS provide the Skype rollups through MS Update?
Hi Jeff,
I see the question is asked briefly above but is there really no way to apply an earlier CU? We have a bunch of Polycom RealPresence endpoints. The latest Polycom firmware only supports CU Feb 2017 (We are currently running CU June 2016). Any advice for this situation?
Cheers,
Rhys
To answer my own question. Yes you find the older updates via the Microsoft update catalog:
https://www.catalog.update.microsoft.com/Search.aspx?q=Skype%20for%20Business%20Server
They are all labelled as KB3061064 (well done Microsoft!) but you can guess which is which by the dates.
Hi ,
I have a question .. All our machines have 16.0.4266.1001 version of SKype client shown in Control Panel->add remove programs, however when I go to skype -> help-> about it shows 16.0.4549.1000
is 16.0.4266.1001 still supported ? I do not see that in the list provided by you in the article
