RE: Exchange 2010 database question
The data you moved became white space in the database. The database will never reduce in size unless you dismount it and run an offline defrag on it to reclaim the space that it was using. If you run the cmdlet below it will tell you how much available space is in the database after the moves you performed.

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.

Thank you! Great info! From: Oz Casey Dedeal [mailto:telne...@gmail.com] Sent: Thursday, February 03, 2011 10:02 AM To: MS-Exchange Admin Issues Subject: Re: Exchange 2010 database question 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 Regards Oz On Thu, Feb 3, 2011 at 10:47 AM, Robert Peterson robert.peter...@prin.edumailto:robert.peter...@prin.edu wrote: I have a database that was growing close to the limits of its “share” space as we migrated accounts into it from Exchange 2003.
