About Exchange 2010 SP1 Hosting Mode

For the last several years, hosted service providers have used the Hosted Messaging and Collaboration (HMC) solution in order to support hosted Exchange deployments. With the release of Microsoft Exchange Server 2010 Service Pack 1, Microsoft has created a new way to support hosted Exchange deployments. Because of this, HMC 4.5 is the last HMC version that will be offered to hosted service providers.

note Note
Microsoft will continue to support HMC 4.5 and HMC 4.0 through December 2011. HMC 3.5 will be supported for existing customers until July 2011.


Exchange 2010 Service Pack 1 Hosting Features

Exchange 2010 SP1 is the first multi-tenant ready Exchange Server version that includes hosting features that will allow hosted services providers to create and manage multiple organizations in the same Active Directory forest. Exchange 2010 SP1 can be deployed using a special "/hosting" switch that installs Exchange 2010 SP1 in "Hosting Mode".

When Exchange 2010 SP1 has been installed using the "/hosting" switch, you as a hosted service provider can create "Service Plans" that makes it possible to enable and disable specific features when deploying tenant organizations. In addition, you can use "Mailbox Plans" which are templates that populate multiple user properties and assign default permissions to new or existing users by default.

When Exchange 2010 SP1 has been deployed using the "/hosting" switch, you as a hosted service provider will also have cmdlets available that aren't available in the non-hosting solution.

Bear in mind though, there are also several features and functionality that aren't available or supported in the hosting version:

  • Exchange Management Console
  • Public Folders
  • Unified Messaging Server role
  • Federation
  • Global Address List Synchronization (GalSync)
  • Business-to-Business features such as cross-premises message tracking and calendar sharing
  • Information Rights Management (IRM)
  • Managed folders
  • Outlook 2003 support (EnableLegacyOutlook)
  • Edge Transport Server role (more specifically EdgeSync support)
  • In-place Upgrades (upgrading current Exchange 2003/2007 org to Exchange 2010)
  • Resource forest topologies (separate Exchange forest and account forests)
  • Parent-child domains
  • Multiple AD sites (where there's a mix of hosted and non-hosted)
  • SSO AD Trusts
  • Dis-contiguous namespace
  • Disjoint namespace


    note Note
    Since Exchange 2010 SP1 in hosting mode doesn't allow the usage of the Exchange Management Console (EMC), it's and recommended hosted service providers develop their own control panel and provision the relevant UI solution on top of it. With that said though, you can of course access the Exchange Control Panel (ECP) as the Administrator of a specific multi-tenant organization, and then manage the organization via the options available in ECP. For instance, when running Exchange 2010 SP1 in hosting mode, you can do basic management tasks such as create mailbox users, distribution groups, and contacts. You can also edit existing user mailboxes and reset passwords etc.





    For more details on what's available via the ECP, see this blog post.


    Are the Hosting Features Included with the "Normal" On-Premise Exchange 2010 SP1 version?

    Some of you might have heard of a so-called data center edition which was referred to as a special Exchange 2010 version for hosted service providers. But such an edition doesn’t exist and there are no plans to release one. Instead all the hosting specific features will be included with the “normal” on-premise (standard/enterprise edition) version of Exchange 2010 SP1. In addition, in order to use the hosting specific features, a special licensing model are required (more specifically Service Provider Licensing Agreement (SPLA) and High Volume Sales (HVS) which you can read more about here).

    note Important
    Organizations that deploy Exchange 2010 SP1 with the “/hosting” switch in either a production or lab environment will not receive any support from Microsoft unless they are a hosted service provider and have acquired the necessary licenses.


    Migrating from HMC 4.5 to Exchange 2010 SP1

    Guidance on how you can migrate (there will not be a direct upgrade option) from HMC 4.5 to Exchange 2010 SP1 is complete and can be downloaded via this link.

    A conceptual overview of the migration planning is depicted in the following illustration taken from the "Migrating from HMC to Exchange 2010 SP1 Hosting document.


    note Important
    Microsoft will not create any guidance on how to migrate from HMC 3.5 to Exchange 2010 SP1 running in hosting mode.


    How Do I Get Started With Licensing Exchange 2010 SP1 as a Hosted Service Provider?

    The licensing model for hosted service providers remains consistent with the model used with previous versions of Exchange. That is a hosted service provider can license Exchange via the Service Provider Licensing Agreement (SPLA) which provides user/month pricing or via High Volume Sales (HVS) which provides SPLA at steep discounts based on volume.

    The starting point for hosted service providers that wish to be enrolled in the SPLA or HVS model can be found here.
