--- Comment #2 from Ingo <ingo.stra...@gmx.net> --- Hi all, I have the same problem on Opensuse Leap 15.0 with KOrganizer version 5.7.3. As Peter before me, I use owncloud to hold my calendar, and when I want to sync events created with KOrganizer to Outlook via CalDav Synchronizer, the events are not accepted because of this line: RRULE:FREQ=YEARLY;UNTIL=19961027T030000;COUNT=16;BYDAY=-1SU;BYMONTH=9 If I understand 3.3.10 Recurrence Rule in https://tools.ietf.org/html/rfc5545 correctly, UNTIL and COUNT are optional but must not both be specified at the same time >>> The UNTIL or COUNT rule parts are OPTIONAL, but they MUST NOT occur in the >>> same 'recur'. I did not have this problem when I was still on Opensuse Leap 42.3 (don't remember the KOrganizer version; KDE app suite was 17.04.2). Could this be fixed, please?
