More than three years after acquiring Skype, Microsoft today said it would rebrand its semi-rival Lync corporate communications platform as “Skype for Business.” The name change will become official in the first half of 2015, when Microsoft releases the next versions of Lync’s clients and on-premises server software as Skype for Business. The Lync service that’s part of some Office 365 commercial subscription plans, such as Business Premium and Enterprise E3, will also be updated and renamed at that time.
