Cannot delete unwanted calendars

30. January 2013 · Write a comment · Categories: Outlook for Mac · Tags: , , ,
I cannot delete any calendars in Outlook 2011 (14.3.0). It does not work with Command + Backspace or Delete (why is this not an option?). It also does not work by right-clicking a calendar - when I do that only a small and empty square of about 1/2 x 1/2 inch opens but no usable contextual menu.

How can I delete unwanted calendars?
