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?
