The most noticeable differences are the new interface appearance, logo and color scheme. All other functions of Skype for Business will be the same as the previous Lync version. We are sorry for any inconvenience or confusion this unexpected update has caused for your agency and employees.
A reboot of your computer should change Lync to Skype for Business. If your Lync has not been updated to Skype for Business after the reboot, please contact the BIT Help Desk for assistance.
The below image gives an example of the old Lync interface (left) compared to the new Skype for Business interface (right).
