I just pushed a pretty big update to org-caldav. Get it at https://github.com/dengste/org-caldav
The short story: org-caldav now does proper two-way syncing. It's pretty much a rewrite, actually. If you're already using org-caldav, you will have to start from scratch after updating. Please read the README before using this version. Most notably, org-caldav will set org-icalendar-store-UID when doing the iCalendar export, so every entry with an activate timestamp will get an ID property like this: :PROPERTIES: :ID: 6cdf8805-8d1a-46ac-94fc-d225cac5f098 :END: If you don't want this, do not use this package. Please report bugs here or in the github tracker. And please have backups. -David
