Outlook—Opening another user's calendar
If you have permission to another user's calendar, but it isn't currently in your list of calendars to choose from, you can open the calendar by following this tutorial.

First go to File and select Open, then select Other User's Folder.

Now type in the username of the person's calendar that you want to connect to.

Select the Folder Type that you want to connect to. In this case, choose Calendar, but you can also choose any of the other types. When you are done select ok.

If you have permission to the other users calendar, then you will be taken to that calendar immediately. If you don't have permission to their calendar, then you will see a dialogue box asking if you want to request permission. Select Yes.
