My end users started archiving their mail and it removed a total size of about 4 gb from their mailboxes. I defragged the database tonight and it only dropped the .edb file about a 1gb and the .stm file didn't even budge.  If I archived 4 gb of mail why wouldn't I have gained it back when I defraged the .edb/.stm database.

1. Turn up online maintenance on the mailbox stores

2. Check for deleted item retention

You should be able to do both of these on the actual "Mailbox store" properties.

If you do not have deleted item retention turned on, then you did not allow enough time for online maintenance to run. I would jack that up to run for a long straight period of time over the weekend, then try again. (But it might be deleted item retention)

Exchange uses a more efficient way of compressing the data stored in the information store databases.

Therefore, although you may have removed 4Gb from users mailboxes, this data may have only been taking up 1Gb of space on your server once compressed within the information store.

If you was to add up all the reported sizes of your mailboxes, I'm sure it would be alot higher than the size of your edb file.
