Ok I had some issues in my environment after installing 2007 and I decided to backtrack and remove 2007. All roles have been removed from the server except the mailbox roll, the mailbox roll will not remove because there is a public folder database. Yet I can not remove the public folder database because it is not mounted, and I can not mount it because it is an empty database there is not even an .edb file. What do i do ? Also is there a way once I remove this roll , to rollback the AD 2007 changes ?
