I have an issue with my calendar app. When I invite external person they get the e-mail with the three options “accept”, “deny”, and “more options”. However, if they click on one of the links, only an error message is shown:
There was an error updating your attendance status.
Please contact the organizer directly.
I already checked the “common” solutions I’ve found (update app, update nextcloud, only unique e-mail addresses on users), but to no avail.
If, however, I have a (local) user in my database with the exact same e-mail address as the external attendee, the links in the e-mail work like a charm and the event is updated correctly.
This seems buggy to me. Or is this the actual behaviour, that only nextcloud users can accept/deny an invitation?
I’m running nextcloud 17.0.3 on an Rapsberry Pi 3b+ with Raspbian 10. I have the LDAP plugin configured to get the users from my LDAP, only one local account for testing purposes.
I can provide a system report link if anyone’s interested in checking the system config.
Is the calendar app updated in nextcloud 18? Is it worth a shot to update to nextcloud 18?
