Database wont shrink  unless you perform offline defrag and take the white 
space out of it.( this isn’t a good thing to do in general , create new DB and 
move MB into it is way better option in many cases) By saying this, when you 
moved out Let’s say 1 Gig worth the data from Exchange database, on the first 
online maintenance Exchange will mark these space as “Usable” and make it 
available to use again next time.

So think as a bucket holds bunch of e-mails ( which grows all the times (-: , 
which is the Exchange database itself, if you your bucket is 10 gig today , 
your backup is 10 Gig each time you do the backup, if you take 5 gig out the 
bucket , you still backup  10 gig since you are baking up the bucket itself and 
that is what you see from windows perspective, even in reality half of the 
bucket is empty,( White space)  Exchange will see the space and re-use it, 
without making the bucket bigger, when there is no white space to use, your 
bucket will start getting bigger and bigger so on…..

I hope this helps a bit

I have a database that was growing close to the limits of its “share” space as 
we migrated accounts into it from Exchange 2003.  I decided to classify some of 
the mailbox accounts differently and moved them to a different database.  This 
all went fine, however the original database did not reduce in size immediately 
since we have a 30 day retention period.

I decided to watch the database and see if it would reduce in size after the 30 
days expired.  The copies of the “moved” mailboxes were visible in the 
“Disconnected Mailbox” section and then did disappear after the 30 days 
retention period...

BUT… the database itself never reduced in size????

What am I missing? IS there something else I need to do to reclaim the space? I 
thought all the maintenance is automatic.

Thank you in advance for ideas and suggestions… still trying to learn how we 
will manage growth in the new Exchange 2010 environment.
