- 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.
- Microsoft supports all subsequent UCS maintenance releases that are Microsoft Qualified. We request customers to check and upgrade to the latest maintenance release before deploying a new software. For All the Latest UC Software Visit Latest Polycom UC Software Release
