Exchange 2010 SP1 Hosting – Part 3 “Hosting Setup”

I gave an overview about Exchange 2010 SP1 Hosting in this post Exchange 2010 SP1 Hosting – Part 1 “Overview” and then I went through Hosting Description in this post Exchange 2010 SP1 Hosting – Part -2 “Hosting Description” , in this post I will go through the Hosting Deployment procedure including setup requirements.

  • Active Directory Requirements

Before Installing Hosted Exchange Server 2010, you should make sure that server has been joined to the network and that it meets the following Active Directory requirements:

Schema Master

Active Directory Schema Master required to be installed on Windows 2008 SP2 & above or Windows 2008 R2.

Forest Functional Level

The Active Directory forest functional level must be at least Windows 2008.

Global Catalog Server & Domain Controllers

Domain Controllers must be running Windows 2008 SP2 & above or Windows 2008 R2.

Domain Functional Level

Domain Functional Level needs to be configured as “Windows 2008” mode.


Hosting Exchange Server 2010 does not support use of RODC or RODC Global Catalog Servers; however Hosting Exchange Server 2010 will function in environment that include RODC DCs or RODC GC Servers, as long as writable DCs are available.

Preparing AD Domain and Forest

AD Preparation is done during setup by extending the AD to support Hosting Exchange Server 2010; administrator can prepare AD before Exchange setup by running a series of setup command as the following:

1. Setup /PrepareSchema /hosting

2. Setup /PrepareAD /Organizationname: [Organization Name] /hosting

3. Setup /PrepareDomain /hosting

  • Installing Hosting Exchange 2010 Prerequisites

Before running the Hosting Exchange Server 2010 setup program, verify that the following software has been installed on the computer that will be running Hosting Exchange Server 2010; these requirements are based on the normal core requirements for all Exchange Servers Roles, and as know Exchange 2010 prerequisites are different if we implement Exchange 2010 on Windows 2008 SP2 from Implement it on Windows 2008 R2, in this post I will consider using Windows 2008 R2:

1. From Windows PowerShell run the following command “Import-Module ServerManager” and press Enter.
