How to remove Exchange 2003?


I'm attempting to remove Exchange 2003 from a server via Control Panel -> Add/Remove Programs
Within the Microsoft Exchange Installation Wizard, I get to the point where it asks for the appropriate action and I select 'Remove'
Then I get the following Pop-Up Message
The component "Microsoft Exchange Messaging and Collaboration Services" cannot be assigned the action "Remove" because:

-One or more users currently use a mailbox store on this server. These users must be moved to a mailbox store on a different server or be mail disabled before uninstalling this server.

All the mailboxes are shown as deleted except the 'SMTP' mailbox & 'SystemMailbox' within each Mailbox Store.

Am I doing something wrong?

Selected the 2nd option to choose 'mailboxes on this server:
found the 3 mailboxes not labeled 'SystemMailbox' and now I get the option to 'Remove' Exchange within the Wizard

one more trick, easier too (sorry)
open adsiedit and browse to the following
configuration - services - microsoft exchange - org name - administrative groups - admin group name - servers - your server - information storet - sg name - store name

view the properties of the store looking at the homeMDBBL

I have had that exact same problem a couple times when retiring an exchange 03 box after a migration.  This is the saved link I have that has resolved the issue every time.
