What is the best practice for removing the Exchange 2003 servers from the enterprise after having migrated all mailboxes to Exchange Online? The AD user accounts are now mail enabled to the Exchange Online mailboxes. The Exchange 2003 Management Console still show the mailboxes, but now with a red cross, after having run the cleanup agent.

How to safely remove all the users from the Exchange 2003 environment and remove all Exchange servers on premises?
