Have you recently restarted your services or have they shut down and
restarted recently at all? Explorer will not update or report the correct
file sizes of the databases until the services have been shut.
Assuming it really grew overnight and is still growing, you might want to
turn up smtp protocol logging and look for a mail loop. Inbox rules can
make an internal loop, a possibility as well. I have found Promodag
extremely useful and quick in spotting loops, because it can be used to
analyse internal as well as external traffic. It has pre-formatted reports
that have helped me determine which mailboxes have generated the most
traffic in a given time frame. You could download a working copy at
www.promodag.com. The eval copy is good for 15 days, which should be enough
time to hunt for a possible loop.
As far as your ims mailbox, the size reported will usually be incorrect
unless you are at the lastest service pack, with all associated hot fixes.
As far as looking inside the ims mailbox, do a search on the Technet DB for
