  • The information in this article doesn't apply to Office 365 versions of Skype for Business, such as Skype for Business included with Office 365 ProPlus.

Skype for Business compatibility with Office 365 and your on-premises environment depends on the system requirements for your deployment:

  • Office 365 works with any version of Skype for Business that is in mainstream support, which includes the latest version of Skype for Business 2016. For previous versions of Skype for Business, only those that have extended support may continue to work with Office 365, although with reduced functionality. For more information, see Microsoft Lifecycle Policy.

  • For Skype for Business Server on-premises deployments, follow the system requirements for your version of Skype for Business:
