Microsoft To Do is a simple and intelligent to-do list that helps you manage all your tasks in one place. You can work through your tasks for the day in My Day and create any number of additional lists to organize your work, groceries, travel, shopping, movies to watch - you get the idea!
In each list you can add as many tasks as you like. Keep everything on track by setting due dates and reminders for each task and starring your most important tasks. Use steps to break down your larger tasks in to more manageable pieces and notes to record extra details. Since all of your tasks are stored on Exchange Online servers, they'll also appear automatically in Outlook tasks.
