A hybrid deployment offers organizations the ability to extend the feature-rich experience and administrative control of their existing on-premises Microsoft Exchange organization to the cloud. A hybrid deployment provides the seamless look and feel of a single Exchange organization between an on-premises Exchange organization and Exchange Online in Microsoft Office 365. In addition, a hybrid deployment can serve as an intermediate step to moving completely to an Exchange Online organization.
A hybrid deployment enables the following features:
A hybrid deployment involves several different services and components:
Microsoft Office 365 Office 365 provides a cloud-based Exchange Online organization as a part of its subscription service. Organizations configuring a hybrid deployment must create and configure this cloud-based Exchange organization.
Hybrid Configuration wizard Service Pack 3 (SP3) for Exchange Server 2010 includes Hybrid Configuration wizards which provide you with a streamlined process to configure a hybrid deployment between on-premises Exchange and Exchange Online organizations.

Hybrid server When the Hybrid Configuration wizards complete the configuration of an Exchange 2010 SP3 server in your existing Exchange organization, that Exchange 2010 SP3 server is now referred to as a hybrid server. Hybrid servers are required for hybrid deployments. They enable messaging features and message delivery between your on-premises Exchange and Exchange Online organizations.
Microsoft Federation Gateway The Microsoft Federation Gateway is a free cloud-based service offered by Microsoft that acts as the trust broker between your on-premises Exchange 2010 organization and the Exchange Online organization.
On-premises organizations configuring a hybrid deployment must have a federation trust with the Microsoft Federation Gateway. The Hybrid Configuration wizard checks to see if there is an existing federation trust with the Microsoft Federation Gateway for the on-premises organization. If present, the existing federation trust is used to support the hybrid deployment. If not present, the wizard creates a federation trust for the on-premises organization with the Microsoft Federation Gateway. A federation trust with the Microsoft Federation Gateway for your Office 365 tenant is automatically configured when you activate your Office 365 service account.

Active Directory synchronization Active Directory synchronization replicates on-premises Active Directory information for mail-enabled objects to the Office 365 organization to support the unified global address list (GAL). Organizations configuring a hybrid deployment must deploy Active Directory synchronization on a separate on-premises server.
