If you ever work with several calendars in Outlook, then you know it can be a challenge to keep everything straight.

There is a way to allow you to see all of your calendars (or those you share with colleagues) at the same time.

With two calendars open, a small arrow will appear next to the name of one of them.  By clicking on this arrow, the calendars merge.  In this view, you can see conflicts, free days, and much more very easily.

To see only one calendar, click the arrow next to the calendar you wish to remove from your view.  Or, to close it entirely, click the “X.”
