Exchange 2007; we have two data stores - one for most of the mailboxes, and one for the 'management' (two mailboxes).  There was 14GB in those 2 mailboxes, but i recently cleaned them all out (each mailbox, according to outlook 'folder size' is under 10MB), but the mailbox database .EDB is stil showing up as being 14.x GB...

i've tried running a 'normal' backup with windows backup, and it didn't shrink after the backup.  also mailbox retention for the database is '0' (which i believe is that it doesn't keep any items after deleted).

What can i do to shrink it?  Those 2 mailboxes are only a total of MAYBE 20MB in size, definitely not the 14.x GB they used to be...

With Exchange 2007 there is no point doing an offline defrag, which simply removes any 'White Space' that might be available.

All you need to do is to move mailboxes from one Database to another and this will achieve the same results as running an Offline Defrag, but without the massive downtime for ALL users within the database.

If you have not maxed out on Databases, then create a new one and move users to the new database, then if empty, delete the old database.

The backup will truncate your log files only not the main DB.

A backup will perform a full backup of the database and the delete ALL of the commited transaction logs. but the DB will remain at the same size.

the behaviour is perfectly normal and i stated earlier - leave it be.
