I'm looking to dcpromo out a child domain - however I have already prepped the domain for Exchange 2010 in the past. Do I still need to do anything to remove the Exchange objects before doing a DCpromo to remove? Exchange is not installed on any servers in that domain, so nothing to physically remove - just the AD objects. I do not want to remove it from the other domain in the forest.

Hi Do you have anything update on your issue ?Terence Yu TechNet Community Support
