Fri, 10 Apr 2026 14:48:27 +0000 https://bugs.horde.org/ticket/9260 importing .ics files failes to load attendees and alarms We are migrating ms exchange to horde/kronolith/postfix/cyrus. Everything went fine so far but we are now stuck on several issues with horde/kronolith (see also bugs 9258 and 9259) making our customer want to go back to exchange. When we import the ics file from ms exchange into kronolith, we loose all attendees and alarm information. The ics file does contain all data and an import into a local thunderbird installation does import all attendees and alarms. If we try to import via thunderbird into a remotely connected kronolith calendar, same problem - no attendees/alarms. We also tried creating an event in kronolith, exporting that event with attendees and importing it back in again. Here also we loose all attendees information. Below the ics used in this test: BEGIN:VCALENDAR VERSION:2.0 X-WR-CALNAME:wverbruggen's Calendar PRODID:-//The Horde Project//Horde_iCalendar Library\, Horde 3.3.9-cvs//EN METHOD:PUBLISH BEGIN:VEVENT DTSTART:20100908T100000Z DTEND:20100908T110000Z DTSTAMP:20100919T192837Z UID:20100919212718.18951ui795i0ye52@webmail.passiefhuisplatform.be CREATED:20100919T192718Z LAST-MODIFIED:20100919T192829Z SUMMARY:test ORGANIZER;CN=wverbruggen:mailto:willem.verbruggen@anagky.be CLASS:PUBLIC STATUS:CONFIRMED TRANSP:OPAQUE ATTENDEE;ROLE=REQ-PARTICIPANT;PARTSTAT=NEEDS-ACTION;RSVP=TRUE:mailto:willem @hig.be END:VEVENT END:VCALENDAR We would be happy to give you access on our systems to run all needed tests/reproduce the problem.
