I am running Outlook 2013 on a Windows 7 computer. Under "Calendar" my Outlook shows a number of calendars (see attachment):
I only use one "Calendar - Outlook". Unfortunately, when someone sends me a meeting invitation the appointment shows up in the second Calendar, which (if I remember) I then need to copy to my Outlook Calendar. Is there any way to make it so that there's only one calendar, and that invitations appear on my main calendar?
