i have found using due date in outlook useful for creatig ‘today’s short list’ of tasks. Then i use the reminder time to set the time i am going to try and work on the task that day. this way it all stays in my task list (off my calendar) and I can use the outlook views like timeline or next seven days to see what is due this week. if i group by due date i any view, rescheduling due dates is as easy as dragging the task to the new due date group. this makes daily task shuffling/reprioritizing take only a few minutes and I’m confident my days short list contains everthing i need/can work on for the day.
