This article applies to Exchange 2013/2016 accounts.

Note: Skype for Bussines Mobile is not compatible with any earlier Lync Server versions (i.e., if your account is  hosted on Exchange 2007/2010, Skype for business mobile will not connect). Domains that were recently upgraded from Exchange 2010 to Exchange 2016 are still using Lync 2010 servers which are not compatible with Skype for Business Mobile.
