Exchange 2007 - large EDB but no mailboxes

I'm looking at a database on my Exchange server and the .edb database file is like 118GB. How do I see what is taking up all that space?

The server the database is on is called MAIL7, so I ran the powershell query;

Get-ExchangeServer MAIL7 | get-mailbox | Sort database, name | ft name, database

it came back and listed only 5 mailboxes. None of them belonged to the Database that is 118GB in size...

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This is by design.

Exchange databases never decrease in size. Once the physical size has grown it never decreases. Even if you move mailboxes to another database the source database physical size does not change.

If you have no mailboxes present on this database then you can simply unmout the database and delete the EDB file.

You will also need to remove Arbitration mailboxes as well before doing so.

It doesn't look like I can get-mailbox -arbitration on my Exchange 2007 server, would there be any other ways of finding those.
