Skype for Business Updates

Skype for Business Updates

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.


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 () is available for Skype for Business Server 2015.



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 but the 5.0 has been truncated fro the following table for spacing purposes.

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.
