Final answer:
In Microsoft Outlook, the status 'Deferred' indicates that a Task is scheduled for future completion, differentiating it from statuses that indicate no start, current progress, or reliance on someone else's actions.
Step-by-step explanation:
Within Microsoft Outlook, when a Task element is scheduled to be completed on a later date, the status that should be selected is Deferred. When a task is marked as Deferred, it indicates that the task is not to be worked on immediately and has been scheduled for completion in the future. This setting is distinct from Not started, which implies no work has begun, In Progress, which suggests work is ongoing, and Waiting on someone else, which indicates dependency on another person's actions before further progress can be made.
