It’s been three months since our last update to Skype for Business Server 2015, which was a rare security update that took us to 6.0.9319.606.
This is build 6.0.9319.619, and it’s a bit of a doozie. It updated seven components on my Standard Edition Front-End, and also uninstalled the now-defunct Skype for Business Online PowerShell module. Check out the scary one I’ve highlighted:

What’s New?
Nothing noted. No cmdlets have been added to the SfB module in this update.
What’s Changed?
Nothing noted.
What’s Gone?
This CU also uninstalls the skype for Business Online PowerShell module, given the product’s recent retirement.
The installer prompts: DONE: SkypeOnlinePowerShell.Exe was uninstalled successfully.
Please install Microsoft Teams cmdlets module for Windows PowerShell manually as a replacement for Skype for Business Online, Windows PowerShell Module. Download it from: https://www.powershellgallery.com/packages/MicrosoftTeams.
Two commandlets have also been removed from the SfB PowerShell module:
- Get/Set-CsUserSettingsPageConfiguration
Known Issues
This isn’t new, but it’s still being included in the kb article:
After you install the January 2019 cumulative update 6.0.9319.537 (CU8) for Microsoft Skype for Business Server 2015, the Unified Communications Web API (UCWA) applications, such as Skype for Business on Mac, a web application for UCWA, and Skype for Business mobile clients, can’t make a call or join a meeting. For more information, please see the following article:

Installation
Here’s the “before” view of it going on to my Lab’s Standard Edition Front-End:
Reboot?
The installer didn’t prompt me to reboot, but I always like to give it one for good measure.

KB 5005513 RTCSrv crashes on all Front End servers in all pools in Skype for Business Server 2015
————-
So are there any risks involved applying CU12 for SfB 2015 servers? I believe this CU12 addresses that issue of RTCSrv crashes, which is a good thing.. Was there any issue with RTCSrv after applying CU12?
Would you please share your feedback.
Thanks,
Raj
Hi Raj,
I’ve not personally encountered any problems with this CU, not read anything of dramas associated with it in any of my online travels, and its longevity in the field (without any hasty follow-ups) are all positive indicators it’s a trustworthy release to deploy.
