As of today, admins have no way to know what is the relation between any attachment in a db and related DAOS object (i.e., cannot know which NLO file corresponds to an attachment).
Also, we must rely on the fact that the status "Synchronized" of the DAOS corresponds to truth (which I found not to be correct on a couple of customers, where we discovered that there were objects left after mail messages had been archived on different server several months before).
So, it'd be nice to have a way to:
1) know the NLO file corresponding to an attachment
2) check if any NLO has a correspondig attachment in any db
