- Customers in Skype for Business deployments should only use software releases that have been qualified by Microsoft or are maintenance releases built on a qualified release. Microsoft qualification may lag behind Polycom GA dates for UC Software so customers are requested to check whether a release has been qualified before deploying new software. Visit Polycom UC Software for Skype for Business Deployments page for a list of qualified releases.
