[...] I think there's a bug in org-icalendar with regards to handling tags. I'm getting an icalendar event like this: BEGIN:VEVENT UID:f90ec513423879f1e09c7c10fc0e15a9-orgmodecaldav DTSTART:20120728T200000 DTEND:20120728T210000 SUMMARY:TerminTest :Tag: DESCRIPTION: <2012-07-28 Sat 20:00-21:00>\n\nSomewhat LOCATION: Büro CATEGORIES:Tag,Termine END:VEVENT Putting this event generates an error from Google, but I think it's due to the :Tag: in the SUMMARY line; the DESCRIPTION looks OK to me. > Combined with MobileOrg this behavior is bothering. > > If an appointment is scheduled, it will not be synced if there is no active > timestamp without the keyword SCHEDULED: Again, this looks like a problem with org-icalendar. I'm not very familiar with that code, but I'll look into it. Thanks for testing, David
