Exchange 2007 Address List Segregation Document
If you read my series of articles about Shared Hosting with Exchange 2007, you'll probably be glad to know that Microsoft is finally releasing the official documentation on how to segregate Address Lists.
If you didn't notice the disclaimers ( ) in the article, I would like to repeat that the procedures described are neither supported nor recommended by Microsoft. I hope they change their position now that the official documentation will finally be released (or at least, part of it).
The document is expected to be released in February, is authored by Dave Goldman, a Microsoft Escalation Engineer and he unveils more details in his blog.
