I get a lot of questions about address list segregation and Exchange 2010. As I have mentioned before that is something Microsoft is working on but it’s not yet supported.
Dave Goldman just posted some news about this on his blog and I suggest you read it.
Yesterday I found Dave’s post about Address List Segregation and wanted to link to it. I get a lot of question in forums about this and some have suggested to do it the way it was done in Exchange 2007 (there’s a whitepaper for how to) but wait!
ADL segregation will be supported but DON’T do it like you did in E2k7!
