I have the following settings in /etc/kolab/kolab.conf
modules = resources, invitationpolicy
kolab_invitation_policy = ALL_UPDATE
invitationpolicy_autoupdate_other_attendees_on_reply = true
resource_calendar_expire_days = 100
According to https://docs.kolab.org/administrator-guide/smtp-content-filtering.html#invitation-policies
this should suffice to automatically update the calender events on participants acceptance, rejections, etc.
Unfortunately nothing happens. The event organizer still needs to manually click to update his calendar event. All other participants do not get the participants status at all.
I have tried to additionally set ALL_UPDATE on the user level. But this did not make any difference.
Has anybody got this working? Am I missing out on something? Or is it a bug?
