#790 CalDav Sync failed: Can't respond to meeting invite.

[Stefan Sichler]

Sync with my Web.de Calendar fails. Most events are not synchronized at all. See attached error log and one of the events that fail to sync.
I'm using DAVdroid 1.9.7-ose on my Android 5.1.1 mobile to create events in my Web.de calender and CalDav Synchronizer 2.27.0 to synchronize it to Outlook 2013.
Note: some of the events in the calendar are created using the web interface of Web.de.

do you sync with an exchange folder?

To avoid the error you can temporarily disable mapping of organizer and attendees in event mapping Configuration (advanced settings)

[Stefan Sichler]

Yes. You're right. That was the problem. Disabling the mapping of organizer and attendees solves the problem.
Eventually, I moved the calendar backing store from my exchange network folder to a local data file and switched on the organizer/attendees mapping again.
It works. Thank you!

Thank you for this cool piece of software! :-)
