Assume that you set the language to French for Microsoft Skype for Business 2015 (Lync 2013). When you send an instant message (IM) to a distribution group that has at least two people offline, Skype for Business 2015 (Lync 2013) crashes.


To fix this issue, install the December 6, 2016, update (KB3127976) for Skype for Business 2015 (Lync 2013).

Note Lync 2013 was upgraded to Skype for Business in April 2015.
