Ouvrir .ics fichiers avec Windows 10 Calendar app

[ForumBot]

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.

Any ideas?

You can change the default app `Settings > System > Default apps > Choose default apps by file type (on the bottom)` for each extension, including `.ics`. I could see in the list The Calendar Windows App, and managed to open an `.ics` I had received.
