Hello!

We've been using Horde with Kronolith for some time now, and 
everything is working pretty well. The thing is, we have one MAC user, 
on Yosemite, that's experiencing the problem described on this ticket. 
Every time he confirms, rejects, or interacts in any way with an 
event, everyone receives a million notifications about it. Is there 
any way to avoid this? He uses Calendar(former iCal) and his iPhone to 
manage his calendars.

this is indeed a showstopper. it might be iCal producing this error,
however horde should not send so many emails especially if set in
user prefs not to send any notifications
Which is why that ticket is open and currently being worked on now.
this is great to hear, thanks!

I have that list too ;-)
ok, so my understanding of Horde after several months of testing for
small companies is: just use the web interface! do not try to use
with os clients, it generates unexpected behaviour especially on OSX.
Currently, for certain use cases, maybe. I would also add "Don't use 
buggy clients" to that list as well.
right, it is too sad the inventor of CalDav/CardDav doesn't care about 
it's own software anymore ... and on OSX there is no real alternative, 
except thunderbird lightning - but which might be to "techie" to 
normal users

another question: isn't horde able to handle internal invitations
(users are known to horde!) just internally, without the need to send
emails?
Because this is not how the iTip standard for event organization
works. We could implement a separate planning infrastructure just for
internal users, but noone has come up with an implementation or
intent to sponsor such development yet.
For what it's worth, I've thought about going down this road a number 
of times while working on ActiveSync related appointment stuff. It's 
still somewhere on my "do when I have time" list, though sponsoring 
would definitely help speed it along.

correct, iCal access Kronolith via CalDAV.
with every new version iCal for non-iCloud users gets worse and worse ...

A user creates a new event in iCal or horde webinterface and
Kronolith places the event to the known user's calendar as tentative.
Only external users (email adresses not known by horde user
management) should get emails (ONCE or on usefull updates ;-)

Where the event is saved is up to the client, nothing we can do about. 
I guess you use iCal to access Kronolith via CalDAV? You didn't 
mention this but from the context this is what I assume.

Yes, this is a duplicate of this and several other tickets.

This might be (is) an iCal issue, but anyway:

When accepting invitations by email (ics) with OSX (10.10.1) using 
iCal the event initially gets added and auto-accepted (!) to the wrong 
calender and and email is send out to all attendees and the organizer. 
Even if "Don't send me a notification if I've added, changed or 
deleted the event" and "Choose if you want to be notified of new, 
edited, and deleted events by email" in the user prefs (Calendar > 
Notifications) are disabled.

then, when moving the event to the correct calendar (all are horde 
carddav calendars) the event gets cancelled (sends email to attendees 
and organizer) and accepeted again (sends email to attendees and 
organizer).

this behaviour seems to be new. it's unclear to me why iCal is 
triggering these emails (maybe https://bugs.horde.org/ticket/3965#c15 
?), even if all notifications are turned off.

another question: isn't horde able to handle internal invitations 
(users are known to horde!) just internally, without the need to send 
emails?
