Microsoft’s Business communications app Lync will soon be rebranded to Skype for Business on Windows Phone. This in itself isn’t new, as we’ve known about the rebranding for months, but Microsoft has outlined some of the changes that are on the way with the rebranding. In addition to the name change, users will see a new layout more like Skype's, with emoticons, and ‘other improvements'. Another, and more substantial change is the “ability to communicate with your Skype contacts using IM, audio call and video call” as explained on Microsoft’s Office support page.
There is also another post from Microsoft’s Office support that outlines what's new on Skype for Business on Windows Phone. One of the benefits of Skype for Business is encrypted local data, including “recent conversations, voice mails, pictures and user settings.” Security is important to companies and the ability to have data stored both on a local device and be encrypted helps keep data safe.
Skype for Business can be a bit confusing since it has similar features and layout to Skype. Microsoft has a brief video explaining what Skype for Business is from a site explaining their service.
Being part of the Skype for Business Server 2015 also gives companies the ability to sync conversations across multiple devices and communicate with people over Skype contacts.
The upcoming rebranding helps unify Microsoft services and brings the option to communicate with Skype users which is a nice feature for businesses.
