We're migrating from Exchange 2003 to Exchange 2007. There are some
significant differences in they way that retention policies work between
these two versions of Exchange. I need to determine who has custom
folders under their inbox - we need to tell these users to move these
folders up one level so that retention policies will work properly. Is
there a way I can use the 2007 Exchange Management Shell, or any other
utility or tool, to determine who has folders under their inbox?
