Forward Emails for a User who has Left

Suppose a user has left a small business (or even a large one) and their manager would like to ensure that no emails are accidentally sent to this user and thereby missed.  To do this in SBS 2011 (Exchange Server 2010) do the following:
Open: Exchange Management Console from the Start Menu.
Expand: Recipient Configuration
Select: Mailbox
Double-click: The user who's left
Select: The "Mail Flow Settings" tab
Double-click: Delivery Options
Check: "Forward to:" and then enter the email address of the intended recipient.

To have emails forward to an non-company email address, this will need to be entered as a contact in:
Recipient Configuration > Mail Contact.
