I know a couple of companies that have done this, several large ones. I wasn't involved in it though.
The couple that I've seen do it are because of SLD issues. See: http://theessentialexchange.com/blogs/michael/archive/2008/04/04/exchange-20 07-and-domain-rename.aspx and http://theessentialexchange.com/blogs/michael/archive/2008/04/03/wrapping-up -slds-and-exchange-server-2007.aspx That being said, many of the earlier reasons for doing so (that still apply) are based on separation of security and responsibility. Exchange and Active Directory are inextricably linked. It's difficult (not impossible, just difficult) to have people responsible for one who are not responsible for the other. Regards, Michael B.

Just curious if anyone has done this yet and what challenges did you encounter? What factors came into play when deciding to implement this way?
