Resolution

Exchange 2010 SP1 is supported starting from POA 5.2.

Exchange 2010 SP1 has two types of installation (modes):
  • Enterprise mode
  • Multi-tenant mode (Hosting mode)
Exchange 2010 RTM has only one type of installation – Enterprise. The RTM version can be upgraded to SP1 and as a result, Exchange 2010 SP1 Enterprise will be installed.

The Enterprise version cannot be upgraded to Exchange 2010 SP1 Hosting mode.

Hosting mode can be enabled only on a new installation of Exchange 2010 SP1 by specifying the /Hosting parameter for the installer.

With Exchange Server 2010 SP1 Multi-tenant mode, the Provider no longer needs a solution like Hosted Messaging and Collaboration (HMC) to host multiple organizations. Multi-tenant support provides the core feature-set of the Exchange Server in a manner that can be deployed to multiple customers in a single installation, and provides ease of management and flexibility of the provided features to end-users.

The Multi-tenant solution available for Exchange 2010 SP1 includes most of the features and functionality available in Exchange 2010 SP1 Enterprise deployments, and 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.

Exchange 2010 SP1 MT (Multi-tenant) cannot be installed in the same Active Directory domain as the Exchange 2010 RTM/SP1 Enterprise mode; it requires a dedicated AD domain.

POA 5.2 can work with Exchange 2010 SP1 Enterprise and Exchange 2010 SP1 Multi-tenant. These Exchange versions should be installed in different AD domains.

Exchange 2010 SP1 Hosting mode requires Parallels Windows Provisioning Engine (WPE) installation in its AD domain.

Separate resource types and Service templates should be created for the Exchange 2010 SP1 Enterprise and Exchange 2010 SP1 Hosting versions.

There are two possible Exchange 2010 SP1 MT deployment scenarios in POA:
  • Only Exchange 2010 SP1 Multi-tenant is planned to be provided to customers. In this scenario, one Active Directory domain is required. Exchange 2010 SP1 Multi-tenant is provisioned with the help of the WPE.

  • Exchange 2010 SP1 and other Windows-based hosted services are planned to be provided to customers. In this scenario, two Active Directory domains are required – the Exchange 2010 MT Domain and the HMC Domain. In the first domain, Exchange 2010 SP1 MT is deployed and provisioned with the help of the WPE. In the second domain, other Windows-based hosted services are deployed and provisioned with the help of the HMC.
