Skype for Business is Microsoft's new enterprise communication tool, serving as a replacement for Lync in the software giant's business-oriented lineup.
It was officially released in April, with new features and improvements coming from its predecessor, but is only now available on Windows Phone.
Windows Phone is actually the first major mobile platform which offers a Skype for Business app, with Android and iOS still having the old Lync 2013 client in their respective app stores. The transition from Lync 2013 to Skype for Business, on Windows Phone, is accompanied by new features.
Skype for Business directly replaces Lync 2013 in Windows Phone Store, being offered as a free upgrade to users, joining Skype for Business Server and Skype for Business Online in the Skype for Business product family.
Compared to Lync 2013, it sports a different branding and user interface, the latter of which closely mimics the consumer Skype client we are already familiar with. But these are not the only changes worth mentioning.
There are also revamped notifications in tow, with Microsoft now offering over 100 of them, improved conversation notifications, which should be consistently delivered to the device the user is active on, beefed-up security, with Skype for Business now toting at-rest data encryption, and the synchronisation of most-recent conversations, which should make it easier to pick up conversations when switching between multiple devices.
Microsoft says that those who are using a Windows Phone 8.1 device will get Skype for Business one way or another: existing Lync 2013 users will receive an update, while new users will get Skype for Business from the get-go.
However, those who are still rocking Windows Phone 8 - for whatever reason - will not be upgraded to Skype for Business. Instead, they will have to keep using Lync 2013 or Lync 2010 until they upgrade their devices to a newer version of the tiled operating system.
Skype for Business is available to download from Windows Phone Store.
