You have been right. Posteo verified that the error is caused by the broken event. After I have removed the event synchronization works now.
Thanks for your support!
Hi there, this reports to DAVDroid 18.104.22.168-ose running on Android 7.0.
I have an ownCloud account registered and synchronisation configured for every new event and every 120 minutes. During synchronisation DAVDroid is correctly fetching new events registered with the ownCloud calendar, but it is not sending the events created on the Android system on which it is installed.
The behaviour is the same if I trigger the synchoronisation manually. New upstream events are downloaded but none is uploaded.
@rfc2822 There is no option in the Andoid calendar to select the DAVDroid calendar.
If it isn’t available, there’s something wrong with your calendar app or the calendar is not available (but in this case, there could be no events shown from it). Maybe have a look through your calendar app settings.
Please note that this is not within the scope of DAVdroid (although I have never heard of such problems). You may also try another calendar app.
@rfc2822 I have a list of about a dozen different calendars. After trying each one by one I could identify those that are linked to my ownCloud account. There is no e-mail address or other symbol that can differentiate between the “Personal” calendar of the phone itself and and “Personal” of my ownCloud account.
Since I do not know the code of either the Android Calendar or DAVDroid, I can not tell why these calendars are not displayed differently as you show in the print screens. But perhaps this is something that should be investigated further.

It depends on what app you are using. Even different versions of the system calendar app matters. Some app will only display the calendar name, which is very confusing to select the right calendar in this case. You can try different third-party calendar manager apps that can display the info more clearly.
