Skype For Business Server 2019


Read this topic to learn how to plan hybrid connectivity between Skype for Business Server and Skype for Business Online or Teams. Setting up hybrid connectivity is the first step in deploying many Skype for Business hybrid solutions.

Hybrid solutions enable you to retain some on-premises control while also taking advantage of online services provided in the Microsoft cloud. With hybrid connectivity set up, and a variety of cloud services available to your online and on-premises users, you can choose to move your users to the cloud based on your schedule and business need.

For example, you might choose to get call control through Microsoft Phone System in the cloud while retaining your on-premises PSTN connectivity. You might also choose to take advantage of other cloud services, such as Cloud Voicemail and Call Data Connector.

This topic describes the infrastructure and system requirements you'll need to configure hybrid connectivity between your existing on-premises Skype for Business Server deployment–with users who were created in your on-premises Active Directory–and Skype for Business Online or Teams.

After you have read this topic and are ready to configure hybrid connectivity, see Configure hybrid connectivity between Skype for Business Server and Office 365. The configuration topics provide step-by-step guidance for setting up hybrid connectivity between your on-premises deployment and Skype for Business Online.
