By now, most users can use both the classic Outlook and new Outlook apps together for email. Either way, the Outlook calendar is accessed as needed via the calendar tab in the left-hand navigation. But what if you want to see your emails and calendar at the same time?

In the new Outlook app, click the My Day button at the top right of the window. It looks like a calendar icon with a checkmark in front of it. With My Day selected, a new panel appears on the right-hand side of the window, where you can see all calendar appointments for today and the following days in chronological order. My Day also has a To Do tab where you can see all your tasks.
