Multi-Tenant Support in Exchange Server 2010 SP1

  • 아티클

With Microsoft Exchange Server 2010 SP1 built-in multi-tenant support, service providers that use Service Provider Licensing Agreement (SPLA) no longer need a solution like Hosted Messaging and Collaboration (HMC) to host multiple organizations. Multi-tenant support provides the core feature-set of Exchange Server in a manner that can be deployed to multiple customers in a single installation, and provides ease of management and flexibility of provided features to end-users.

The hosting solution available for Exchange 2010 SP1 includes most of the features and functionality available in Exchange 2010 SP1 Enterprise deployments, but also includes features and functionality that will allow you to create and manage tenant organizations.

Microsoft Exchange Server 2010 SP1 will form part of the suite of multi-tenant capable products that will replace the Hosted Messaging and Collaboration 4.5 solution.

What's not available in Exchange 2010 SP1 Hosting Mode

Exchange 2010 SP1 doesn't support the following features in Hosting mode:

  • Exchange Management Console
  • Public Folders
  • Unified Messaging Server role
  • GalSync
  • Federation
  • Business-to-Business features such as cross-premises message tracking and calendar sharing
  • IRM
  • Outlook 2003 support (EnableLegacyOutlook)
  • Edge Transport Server role

What's Available in Exchange 2010 SP1 Hosting Deployments

The following features and functionality are unique to hosting deployments:

  • Hosting Installation   When you install Exchange 2010 SP1 for hosting deployments, you will run the installation from the command line and include the /hosting switch. Once installed, your servers will be running in Hosting Mode.
  • Tenant Organization Configuration   Because you will be creating and managing multiple organizations in the hosting deployment, you can use cmdlets and parameters that aren't available to Enterprise deployments. For more information, see Checklist: Create a Tenant Organization.
  • Service Plans   A service plan allows you to enable or disable certain features when deploying tenant organizations. They simplify tenant administration by automatically setting up feature configuration and automatic feature provisioning of mailboxes. In addition, service plans allow you to grant the correct set of RBAC permissions to tenant based on available features.
  • Mailbox Plans   A mailbox plan is a template that automatically populates multiple user properties and assigns default permissions to new or existing user accounts. You use mailbox plans to provision accounts for a particular user population with a common default configuration.

For more information, see Understanding Service Plans and Mailbox Plans.
