I am sorry that I haven't posted in a while, as I spent most of the last couple months investing a ton of time in to getting this white paper finished for everyone. I just have finished the Address List segregation document. I just got clearance from Tom Di Nardo who is a Senior Technical Writer with the Exchange Product Group and the brains behind getting this document out to the world.  Tom has been helping me around the clock on this document that we will have this ready and released in our February technical refresh. This is a 50 page comprehensive document on how to set up address list segregation with Exchange 2007.

This document will cover the following:

1. Introduction to Address list segregation
2. Supported and Unsupported Configurations
3. Planning for Active Directory Partitioning
4. Global Address List Configuration
5. OWA and Outlook attribute configuration
6. Active Directory schema configuration
7. Permissions, Policy, User, Group and Organization, GAL and OAB configurations

NOTE: What this document is *not* a replacement solution for a HMC (Hosted Solution). This document is meant to be used for companies that need to separate out their internal support structure. If you are going to be hosting other companies or organizations you will want to go towards a Hosted Solution and this document is *not* for you.

I want to give a big thanks to the following people that made this possible:

1. Tom Di Nardo, Senior Technical Writer - Who spent I can't tell you how many hours writing, reviewing, writing scripts and testing this.
2. Michael Barta, Support Escalation Engineer, Microsoft CSS Enterprise Messaging Support - Who spent a *ton* of time putting the original draft together for me. Michael wrote a lot of the Powershell scripts as tested this as much as I did. Michael spent many hours with me and Exchange Development team to come up with the best solution.
3. All of you that waited patiently for this document for so long.

Together we made this possible for all of you.
