Late last year, Microsoft announced that it would be re-branding its Lync enterprise chat and video service as Skype for Business. After launching a technical preview for the same on Windows desktop in the month of March, Microsoft is now dogfooding (internally testing) the Skype for Business app for Windows Phone.
As hinted by the Skype team during their recent AMA session, Skype for Business is listed on the Windows Phone Store, but can only be downloaded by Microsoft employees at this stage. We'll let you know once it's available to download publicly. Until such time, mobile users can connect using Lync 2013 for Windows Phone.
Thanks for the tip Todd!
