Skype for Business Server 2015 February 2017 Cumulative Update

Happy valentines ! I Noticed last night on twitter thanks to @Luca_Vitali that a new Cumulative update was released yesterday for Skype for Business Server and there a lot in this one Smile !

Windows Server 2016 is mentioned which is great and cant be long for this to be a supported OS for SfB Server now. I did check TechNet for SfB OS’s and 2016 isn’t listed yet. Also it again notes an E911 fix for non windows auth clients so this may be critical update again. There seems to be have been a few E911 bugs recently.

Highlights

Fix for SfB Installer on Server 2016 ! So it wont be long now people !
E911 fix for non windows auth clients
Push notification support for iOS and Android
Presence and contact card updates
Skype web sdk update for accepting across-domain anonymous meeting join requests

It also noted that This update enables Location-Based Routing to support the Skype for Business mobile clients which is interesting.

Version Number for this update – 9319.277
