aparently it is just a rename. i don't deal with any clients that use it anymore, but last i heard they are just adding lync support to skype, and decided to kill one of the brands. cleverly they killed lync.

They did say they would make the Lync client more like Skype. Which is insane, as Skype is one of the worst pieces of software I use on a day-to-day basis. Lync is a far cleaner, nicer, client.

Also, ffs, "Skype for Business".
