We've got a Win SBS 2003 SP2 server. Were running MS exchange and have noticed that there is quite a discrepancy between the size of the mailboxes shown within Exchange System Manager and the priv1.edb file. Adding the mailboxes in System Manager, we get about 8GB of space, but the priv1.edb file is about 14gb. I know that they won't ever match in size but I'm concerned about how far apart they are. We've ran an offline defrag but it doesn't appear to shrink down the priv1.edb file at all. Can anyone shed some light on weather I need to be concerned and what I should be doing about this situation?
