I am trying to add an appointment I have been sent via email to the calendar app.
What happened so far:
Windows 10 opens the attached .ics file with Outlook and proceeds to add it to one of the inactive calendars in there. I don't want to use Outlook (or any inactive calendars which don't sync).
I saved the .ics file on the desktop and tried to "open with" but found that "open with" doesn't give me the option to choose a random app or the calendar app but only Outlook, an assorted list of some applications including Notepad, and the Windows Store.
I tried to set a default for calendar in the Windows 10 "All settings" -> "Default apps" and found that no program is configured for "Calendar". When I try to configure one (the calendar app), it says it cannot find any suitable app on my PC and proceeds not to find a suitable app in the Store.
So I finally gave up and figured I ask someone.
