Hi David, hehehe well we just started testing it a bit. Don't frighten there are problems... ;) So far, we could see appointments in the SOGo calendar which magically appeared after calling sync. Just to get started with problems: I noticed that there seems to be a problem with syncing events back to org. E.g., if I move a entry from within org-caldav, after sync I get a message about sync caldav->org, they still appear at the same position in the org-mode fie but the entry has no date at all. The old entry can be found in org-caldav-backup.org Furthermore, I notice, that entries have a 1 hour shift (an appointment at 9:00 in org appears as 10:00 in SOGo). I set already the timezone but the problem remain. Since 1 hour is exactly the time difference between UTC and the local timezone (Europe/Berlin), as well as summer/winter time settings, I would assume the problem is related to this. I know that this kind of stuff can be a mess. I would like to say that I really love the debug and sync messages. For those kind of procedures, I always frighten that something goes wrong unnoticed and I was really happy to see a the user readable status messages. I also noticed the files org-caldav-2094e16.el and org-caldav-backup.org. However, they are stored in my .emacs.d folder. Would it make sens to have an option to save them relatively to the org-file? E.g. relative to the path set in org-caldav-files? That would help to keep infos together and might be even a security concern (e.g., you might forget to move or delete backup infos in .emacs.d)!? Thanks, that's good news. I'm actually pretty surprised that it works > right out of the box. > > > Any plans to sync tasks too? > SOGo calendars allow to set events and tasks (not sure whether tasks are part of the caldav specs). From what I can say they differ only in the fact that a task has a certain deadline and can be marked done. Thus, this would be equivalent to a TODO DEADLINE entry in org-mode Thanks again for this great work and please tell us how to help you to get SOGo 100% compatible, we would like to help as much as we can. Greetings Torsten
