Works with my davical server, as it seems! But when I refile an entry from org-caldav-inbox to org-caldav-files it gets downloaded into the inbox again the next time I sync. That's not supposed to happen, is it?
It'd be neat if editing of synced events worked to a higher extent. Do you plan on working toward this? Busy times are announcing themselves and this is what I need to get through them ;) -- Philipp Haselwarter
