I've recently ran an offline defrag on my priv store on exchange 2003 as it was close to 75gb. And it reduced by a couple of gig, but what i've noticed is if I count up the number of mailboxes (about 30) and multiply by their average mailbox size (800mb), it only comes to about 25gb, but the priv store is around 68gb and if you look in the event log, the online defrag reports the store at 68gb too??
How comes I have approximately 30gb's of data that I cannot find? Again, I've recently ran an offline defrag which should shrink it?
