So I go to Exchange Management Console
Then I expand Microsoft Exchange > Recipient Configuration > Mailbox
... find the person i want to edit right click them and click properties.
Click the E-mail addresses tab
Click Add (green +)
Put in the new email address the employee wants
Uncheck "Automatically update e-mail addresses based on emails address policy.
Set the new email address "Set as Reply"
Then I go to the users OWA and setup a rule for auto replies saying email me at my new address from the employees old address?
