RE: Exchange 2003 store size mystery

"eseutil /ms <dbname>" will give you the full space utilization layout
of your database.

It's pretty easy to write a WMI script that shows you dumpster contents
too, if you really think that that might be an issue. Check out the
Exchange_MailBox class of WMI.

No, unfortunately I did not get an email from you at that time.  Would
you please re-send your recommendation?

Thanks!
