Invitations and Events in Thunderbird/Lightning with cPanel CalDAV

We have been using Lightning and CalDAV for some years, mostly trouble-free. When we moved to a new host, we decided to stop using Baikal as the CalDAV server and take advantage of the built-in CalDAV server in cPanel.


We have run into two problems related to events/invitations, and I don't know how to fix them:

1. When a person gets an invitation and accepts it, an email is generated and sent to every other participant. If they so much as change the reminder time, or get the reminder and choose to snooze for some period...yep, a whole nother round of emails is sent out.

This was not happening with the Baikal server. I have gone into Horde, and done Preferences|Calendar|Notifications, and set "Choose if you want to be notified of new, edited, and deleted events by email:" to NO. I checked the box for "Don't send me a notification if I've added, changed or deleted the event?"


I remember in older versions of Thunderbird/Lightning, you were asked whether you wanted to send out notifications to the other participants, but there's no longer an option there for that, I guess it's expected to be set on the server now. People are quickly getting annoyed at the flood of emails surrounding rescheduling of a simple meeting.


2. The second thing is that these notifications show YOU as the organizer (whoever YOU is)--so that every copy of T-bird shows that person as the event organizer. That's bad enough for an in-house event but looks weird when we're responding to a client event that they set up.


We are on Thunderbird 45.8.0 (current release)--mostly on Win 7 though some people may have Win 10.
Horde Groupware 5.2.14
uname -a
Linux 3.10.0-514.10.2.el7.x86_64 #1 SMP Fri Mar 3 00:04:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux



Any ideas how to fix either of these? I think we're going to be in trouble if I can't fix these issues quickly.

Hello,

These seem to be issues with Thunderbird as opposed to how CalDAV is implemented server-side. You can report issues related to Thunderbird at:

Bugzilla Main Page

I believe the second issue you referenced already has an existing case open:

1217505 - CALDAV - event organizer with a read-write subscribed calendar

Thank you.

Thank you. Since my first post, I have done some more research and I actually think it is this issue:
Tickets :: [#13664] accept event to Horde CalDAV calendar from Thunderbird Lightning parses Attendees
Tickets :: [#13790] Kronolith sets attendee as organizer when accepting through mailclient
I have posted the comment on the Thunderbird forum as well:
Using Lightning with CalDAV on cPanel--any way to ... - Mozilla Support Community

What is described under those Horde tickets is exactly what we experience, so I think it's an issue with Horde and can't be resolved by cPanel or Thunderbird. Fortunately there IS a workaround: when you get an email with an invitation you want to accept, open it in cPanel webmail (using Horde). You'll be able to accept or decline via a pulldown and button, and doing it that way doesn't trigger the bug.

Hi, i just want to add: i have just had to switch away from Thunderbird / Cpanel CalDAV (while i love Thunderbird and open standards) because of this issue. Meeting invites are so often-used, this really needs to work flawlessly.

Still an open issue!!

to all who posted here: i finally got multiple IMAP and exchange accounts in combination with calendars and calendar invites working, not in Thunderbird but in Outlook. Pity cause i prefer Thunderbird, but i just need calendar invites to work appropriately.
For those who are interested, here's how to get it to work in Outlook (also not easy, but after initial setup it works):
