Mastering Microsoft Exchange Server 2007 SP1

The new message transport architecture of Exchange 2007 provides a wide variety of new capabilities that can make your job easier. While these new features are not going to be complete compliance solutions for any but the smallest of organizations, they provide a consistent, manageable way to establish controls across your organization.

Message classifications provide a way to visibly tag selected messages and show that they require specific treatment. On their own, they're merely advisory, but combined with transport rules and mailbox rules, they can become powerful selection criteria for managing messages and ensuring policy compliance. The catch is that while they work out of the box with OWA, using them with Outlook 2007 requires you to get your hands dirty copying files and adding Registry entries.

Transport rules give you a powerful, centralized method for creating automated policy enforcement in your environment. You can create rules on both Hub Transport and Edge Transport servers, although they serve slightly different purposes.

Journaling is still around and better than ever in Exchange 2007. In addition to journaling to mailboxes within the organization, you can now designate external recipients to send reports to. Standard journaling enables journaling on a per-database basis, while premium journaling allows you create journaling rules targeted to specific groups or even individual users.
