Allow administrators to pre-assign a mailbox to be disabled on a schedule.  Currently, IT is advised a few hours before an employee is terminated or quits and it would be very helpful if the changes to the user's profile could be scheduled.  Such that on X Date at Y Time John Doe's mailbox is Disabled for access. There should be two values same as the current disable mailbox settings. Then at Y on X the account is automatically changed.  

Ideally, if admin could also enable or setup a forwarding to be enabled at the same time that would be awesome. 

If any of this can already be accomplished through a API I would appreciate knowing how to task drive it. d
