I could be something with Sabre Vobject exeption (https://github.com/fruux/sabre-vobject/blob/master/lib/ITip/SameOrganizerForAllComponentsException.php) but I don't know. How to detect which particular calendar entry lead to this exception? Http 500 code indicate that the problem is on the server side and not MS Outlook / outlookcaldavsynchronizer.

My server side ics files are named like this:

You changed one meeting in Outlook (or got an meeting update). It must have been an recurring meeting with one exception with a different organizer. I am not sure how that can be created in Outlook

A fix could be sync with mode Outlook <- Server (Replicate) once so that the server overwrites that meeting again.
