SUMMARY I received an invite as an ICS file on my main mail address, which is not a GMail address. I wanted to add it to my Google Calendar (different account, but both configured in Kontact), so I could access it from my Android phone. KOrganizer reported "1 incidence was imported successfully" in a blue bar at the bottom of the screen. However, the event wasn't added to the calendar. STEPS TO REPRODUCE 1. Create an ICS file with a non-Google e-mail address as the attendee. 2. Try to add that event to a Google calendar. OBSERVED RESULT In the logging of Akonadi, I found this: org.kde.kgapi: Bad request, Google replied ' "{\"error\":{\"errors\":[{\"domain\":\"calendar\",\"reason\":\"participantIsNeitherOrganizerNorAttendee\",\"message\":\"The owner of the calendar must either be the organizer or an attendee of an event that is imported.\"}],\"code\":400,\"message\":\"The owner of the calendar must either be the organizer or an attendee of an event that is imported.\"}}" ' org.kde.pim.google: Got error: KGAPI2::EventCreateJob(0x564b09f142f0) "Bad request." EXPECTED RESULT Ideally, KOrganizer would rewrite the attendee field to match the e-mail address that is tied to the calendar, when the attendee is a different mail identity of the user. In any case, KOrganizer should not report a successful import when Google's server rejected the API call.
