> The server will not allow an attendee to store an event that has another user (also hosted on the server) as an organizer, if the organizer's copy of the event is not present. In your case, create the initial event in a server calendar rather than a local calendar as the organizer - then it will propagate correctly to all attendees and stay in sync as changes are made.

Hi Cyrus.
what you mean with "create the initial event in a server calendar". The typical workflow is that we receive invitations from external users via email. it looks like that sometimes we are able to import and accept those kind of events. but some users not. It is very difficult to reproduce.

we also found at the access and error logfile the following lines

what does that mean: "can not change organizer"?

Thanks for any hint or advice. This is really critical for us because we are not able to collaborate with anyone outside (people who don't use the server).
