Exchange 2010 doesn't free up whitespace automatically. You either have to live with it, or create a new database and move all of the left-over accounts and delete the database.
EDIT: I forgot that if you don't mind dismounting your database and you have a bunch of free disk space available (equal to amount of whitespace) then you can do an offline defrag using eseutil /d. See http://exchangeserverpro.com/defrag-exchange-2010-mailbox-database
Three possibilities I can think of:
You need this hotfix: http://support.microsoft.com/kb/2621266 (doubtful, but maybe)
Your retention period for deleted items or deleted mailboxes is getting in the way. You can try setting those to both to 1 day and then waiting until the next full backup to check again.
You aren't purging the disconnected mailboxes after they've been moved (goes with #2 actually)...see here: http://www.howexchangeworks.com/2010/09/purge-disconnected-or-soft-deleted.html
Hope that helps.
