My AD/Exchange Environment has gone through a number of upgrades over the years.
Exchange 5.5 - 2003 and now finally to 2007.
One thing that's bugged me for a while, I think since we were on Exchange 2003, is that in "Active Directory Users and computers" under the Users Container, I can see an entire duplicate of my OU structure which is empty. So, just the containers, replicated exactly as you see it under the Forest Level. The containers contain no users or computers, it's just a complete copy of the OU structure, but with nothing in it.
Does anyone know why these empty containers might be there?
