Forefront TMG enables you to protect your organization from spam, viruses and other e-mail-based threats.

  Note:
  You can download evaluation software of Exchange Server from the Microsoft Download site.

• Forefront Protection 2010 for Exchange Server.
  
  

It is recommended that you install these mail protection technologies (and their prerequisites) on each array member, in the following order:

1. Install Active Directory Lightweight Directory Services. For instructions, see Installing Active Directory Lightweight Directory Services.
   
   
2. Install the Exchange Server Edge Transport Transport role. For instructions, see Installing the Exchange Server Edge Transport role.
