Office 365 (Outlook 2016 for Mac | Outlook 2011) - View multiple calendars at the same time
One can see multiple calendars at the same time, in a stacked overlay view to help see availability across calendars.
- On the Navigation Menu (Commands at the bottom left corner of the Outlook window that enable you to quickly navigate to Mail, Calendar, People, and Tasks), click Calendar.
- In the Folder Pane (The column on the left side of the Outlook window that contains folders for each view, such as Mail or Calendar. Click a folder to show the items in the folder. Formerly the Navigation Pane in earlier releases.), check the box for each calendar you want to view.
Each calendar you check opens on the same page, each calendar is transparently stacked on top of one another. In this combined calendar view -- overlay view -- it's easy to identify free/busy times among multiple calendars. When you see an empty time slot, you know there's nothing scheduled on any of the calendars in the overlay view.
Tip You can drag calendar items from one calendar to another to make a copy, as long as you have the required permission.
When you no longer want to view a calendar, uncheck it in the Folder Pane.
To add a calendar from another user, select Open Calendar.
And Type the other User's email in, if you have permission you will be able to view their calendar. If not you may need to ask the User for permission.
