Unable to publish calendar

[paul.raison]

Hi,

I'm trying to publish an ICal calendar on Mac OS X to Open-xchange, but I get the following error:

"HTTP/1.1 409 Conflict"

There is no entries on the Open-xchange calendar for the account, so cant see any conflicts. Any ideas?

Paul

Any ideas where to start to look?

Hi Paul,

are there any error messages at the groupware logfile at the server (/var/log/open-xchange) when starting the sync process?

Greetings

Hi Martin,

The error log has the following:

Does this help?

Yep, it seems the sync device does not set a owner for the appointment, this is mandatory for the open-xchange server. In most cases the owner ("principal") of a appointment is the current user, maybe the device allows a configuration to send the users e-mail address as owner.

There are no principals in iCal.

The "problem" is that the server doesn't allow clients to blindly overwrite folder contents. You first have to download the old contents, and then upload the new appointments together with the existing appointments.

[paul.raison]

Here is the file that Ical is sending to the OX server. What key is missing from this file?

Nothing is missing. Ignore Martin's reply.

You have to download before you can upload.

[paul.raison]

But I have nothing in the OX calendar at present and I have already tried downloading from OX before trying to publish back. Should I try create a new OX account and publishing the calendar to that?

[Viktor Pracht]

You must download with the same software which does the upload (same user agent string).

The iCal interface is designed for fat clients which first read the existing data and modify it, not for overwriting everything in a folder.

[paul.raison]

OK, I understand now, it's the User Agent string that must match. Previously, I had downloaded the ics file from OX with a web browser and imported it into Ical before trying to publish. I have done as you suggested and subscribed to the OX calendar with Ical and then tried publishing and it now works!

Many thanks for your help.

Paul
