SUMMARY

One of the few features I'm sorely missing in AKonadi/KOrganizer is support for the "cancelled" status for appointments and tasks (though quickly checking the RFC (https://www.rfc-editor.org/rfc/rfc5545) for the correct terminology it's also a status for journal entries).  I find it useful for keeping track of certain tasks especially (e.g., "I considered this, but decided against it"), which just deleting them does not sufficiently cover.

Ideally support would also include the necessary UI for cancelling items, though at least correctly displaying cancelled items would be a good start.

This feature is supported by Nextcloud (which is what I use) and various Android apps.

(The only bug or ticket I was able to find was https://bugs.kde.org/show_bug.cgi?id=345570, which has been closed for ten years now and merely concerns the *display* of cancelled items.)

Can confirm for KOrganizer 6.5.0. A correctly set STATUS:CANCELLED still gets ignored.

I'm not familiar with how far KDE PIM tries to implement iCalendar standards. But I can tell that from a user's perspective, it's a nasty surprise to see the very same entry that Android calendars, Thunderbird, Nextcloud calendar and others mark with strikethrough text appear as a normal entry in KOrganizer.

My current workaround are square brackets in the SUMMARY field.
