Just in case you missed it, Exchange 2010 SP2 was released earlier this month. The following features and functionality has changed since Service Pack 1 for Exchange 2010:

• Hybrid Configuration Wizard
• Address Book Policies
• Cross-Site Silent Redirection for Outlook Web App
• Mini Version of Outlook Web App
• Mailbox Replication Service
• Mailbox Auto-Mapping
• Multi-Valued Custom Attributes
• Litigation Hold

I wanted to call out a couple of these that I have been eagerly awaiting:

Hybrid Configuration Wizard
Exchange 2010 SP2 introduces the Hybrid Configuration Wizard which provides you with a streamlined process to configure a hybrid deployment between on-premises and Office 365 Exchange organizations. Hybrid deployments provide the seamless look and feel of a single Exchange organization and offer administrators the ability to extend the feature-rich experience and administrative control of an on-premises organization to the cloud.

Cross-Site Silent Redirection for Outlook Web App
In Exchange 2010 SP1, there was three types of redirection for OWA in Exchange 2010 on-premises:

• Manual Redirection
• Temporary Manual Redirection
• Legacy Silent Redirection (for Exchange 2003/2007)

With Exchange 2010 SP2, you can enable a silent redirection when a Client Access server receives a client request that is better serviced by a Client Access server located in another Active Directory site. This silent redirection can also provide a single sign-on experience when forms-based authentication is enabled on each Client Access server.
