Delete the local Exchange Server mailboxes
Applies To: Windows SBS 2008
To prevent confusion and to simplify your efforts to support your e-mail users, it is recommended that you delete the local Exchange Server mailboxes as soon as possible after you migrate the contents of the mailboxes. You must delete or disable mailboxes before you can remove Exchange Server from your server.
By default, Exchange Server disconnects deleted mailboxes for a period of 30 days before they are permanently deleted. You can reconnect them at any time during this period. For more information about deleting and recovering mailboxes, see “How to Recover a Deleted Mailbox in Exchange” (http://go.microsoft.com/fwlink/?LinkId=147495).
