Summary: Skype for Business Server 2019 or Skype for Business Online administrators can use these tables to understand what features are supported on which clients.

Before you deploy or upgrade to Skype for Business Server, check which clients are already in use in your organization. Use the tables below to understand the feature support impact on those clients. This can help you communicate changes to users, pace the roll-out process, and fully understand the benefits of upgrading to the latest client.

Some features available with Skype for Business Server 2019 are not available in Skype for Business Online; see Online or Hybrid user account limitations for specifics. Skype for Business Online Admins may want to refer to Skype for Business Online Service Description for information on the different plans available to them.
