A hybrid deployment is a deployment in which some users are homed on-premises and some users are homed online, but the users share the same domain, such as contoso.com.
You can configure your on-premises deployment for hybrid with Lync Online and use Active Directory Synchronization to keep your on-premises and online users synchronized. You can also configure hybrid deployments for integration with other Microsoft Office 365 applications, including Exchange Online and SharePoint Online. This section guides you through deploying the applications required for a Lync Server hybrid deployment, and then configuring your deployment to enable it.
