multiple calendars

[Guest]

Somehow I have managed to create 4 Calendars of the same data. How did I
manage to do this, and how do I delete all but 1. Holidays and events are
occuring 4X?

See if the info here helps since it seems like you've got the same PST
(Personal Folder) file open multiple times:
