With the release of Exchange Server 2010 SP2 later this year, we will add a new feature known as Address Book Policies. Following this addition, hosters who wish to deploy the standard on-premises configuration of Exchange and use ABP will be supported.
As you may have read in a recent post over on the Exchange Partner Marketing blog, our view on whether to host Exchange using Hosting Mode or the standard on-premises configuration is changing in response to feedback we’ve had from both hosters and customers. We recognize that the Hosting Mode configuration of Exchange we released as part of SP1 provides a more robust multi-tenant solution, but lacks some of the features available in the standard on-premises configuration. Many of these are key features which customers are asking for, like Exchange Unified Messaging. We want to enable our hosting partners to offer the same rich feature set that our on-premises customers are used to. As such, with the release of SP2 for Exchange Server 2010, we intend to broaden our support stance to include hosting the on-premises configuration of Exchange in a multi-tenant environment.
