I need outlook to remind me of the pending tasks before exiting when I click the exit button

I'm sure all of us would like to complete all the tasks that are assigned for today before leaving the office. But how to make sure we did? Sure we can go to tasks and check. But when I'm in a hurry I miss out checking tasks. 

So I need outlook to remind me of the pending tasks before exiting when I click the exit button. Is it possible?
