@rfc2822 said in Declined events are not marked as ATTENDEE_STATUS_DECLINED: Indeed, it’s technically possible to tell the Calendar API a different email address than the account name (default is account name). We’re planning to make an “email address” CalDAV account setting in DAVx5 for this purpose. However, at the moment, the account name will be used as email address. That would be great, thanks for planning that! You have renamed the account to a name that’s already existing. DAVx5 didn’t handle this error properly, but it should now be fixed (show an error message instead of crashing). It is likely possible these entries 23 and 24 in the service DB came from an old backup that failed. I didn’t have an account listed in the app with that name already. Thank you for having improved that! Perfect, so I’ll set this as solved. Absolutely. We hear this from time to time, and I have often tried to reproduce it, but never succeeded. If you find a way to reproduce this, please let us know in a new thread. I can create a new topic, no problem Thanks for you help!

@rfc2822 Ah yes ! Thanks.

The issue has been fixed in Calendar v1.6.3

@maximilian said: The ROLE is still different from yours, but that shouldn’t make a difference, right? Right, as long it’s a role where RSVP makes sense. You could have a look into the source code of AOSP calendar to find more information. I cloned the repository and grepd for it (grep -Ri role .) but I got no hits… In Android terms, it’s called ATTENDEE_TYPE (see SDK docs). I don’t know, but I guess that OwnCloud doesn’t support CalDAV Scheduling. If I understand it correctly, then owncloud uses sabre for the calendar - and they say on their website they support scheduling. I have verified that my owncloud installation has the required settings… As far as I know, OwnCloud is based on SabreDAV, but it has a special way for many things. Maybe CalDAV Scheduling is just not enabled in OwnCloud for some reasons? From my point of view the issue is now resolved at the DAVdroid end: I know that I can’t use the Google Calendar App (=> use Etar) and I need to fix my owncloud / switch to something else (do you have recommendations?). I still didn’t find anything that’s matching all my needs https://davdroid.bitfire.at/configuration may be a good starting point. If it’s about feature completeness, I think Contacts & Calendar Server may be interesting, but I don’t have experience with it.
