No. When items are permanently removed from the database the resulting
empty space is used for storing new items. Onlly when the empty space is
all used up does the database file size increase.

Hi Carl,
Yes there is incoming traffic and I believe it is much higher that clean up
especially due to attachments. But I thought this is the way it works:
* Let's say for example I have a 10 GB database
* Cleanup policy deletes 1 GB, so the database stays at 10 GB but will
shrink down to 9 if I do offline defrag
* Meanwhile if I receive new emails, database goes to 11,12,13 GB and
higher still having the potential of loosing 1 GB
* Doing offline defrag bring it down 1 GB as example from 13 to 12
Isn't it the way it should be?

If you purged deleted items worth 500 MB/week for 4 weeks and never received
any new mail at all, then you should get back 2GB of real space for an
offline defrag.
Seems likely/possible though, that you are receiving new items, and probably
more volume in new items than in the old items being deleted/purged. This
would be the case with most organizations.

Subject: [ExchangeList] free space after offline defrag
Hello everyone
I just have this strange feeling. We got a 2003 SP2 server. I have a mail
box manager policy that cleans up junk mail and deleted items after a week.
Every Sunday night I get a report that at least 500 MB is deleted. So when I
do the offline defrag once a month at least I should get 2 GB of free space
back from database. But that doesn't happen. As an example I ran a defrag
last night after 2 month wait and I only got 120 megabyte back. Something is
not right and my database keeps growing larger. Any idea?
Thanks
