Hey,

i installed Kontact and set up all my accounts.

Everything is working fine, even gmail and my work Office 365 exchange shared calendar.

The one thing not working is the synchronization with apples caldav server.
I set up a new dav Groupware ressource, added my username and a special third-party-app-password.
The account SEEMS to be working, Kontact can get all the calendars in my icloud account. But no data is actually sync'ed.

I tried to get some usefull information out of akonadiconsole, but i cannot find any error. If i synchronize the dav groupware account through akonadiconsole i can see some messages in the debugger view, but nothing leads me to any kind of problem.

Any ideas what i can do to find the issue behind the missing calendar events?

I use Kontacts on Kubuntu 20.04. But it is not a Kubuntu problem. I just set up a VM with opensuse tumbleweed and can reproduce the same behaviour in Kontacts. The tumbleweed vm has kontact 5.13.3 running.

Any tipps are appreciated!

Edit 1: I tried the caldav.icloud.com address as well as https://pXX-caldav.icloud.com/<DSid>/calendars/<pGUID>. Both adresses with the same result.
Edit 2: Maybe it's related to this bug https://bugs.kde.org/show_bug.cgi?id=386985

I have the same problem with CalDav and iCloud. With addressess i cannot even get Carddav working with KAddressbook. Everything works like a charm with evolution. though as much as i want to use kontact these drawbacks make me stay with evolution.

I am having this issue. Could somebody please advise what I need to do? I can load the calendar names, but no events show up.

The only items that show up (and delegate across iCloud to other devices) are events that I create from within Kontact/KOrganizer.

Kontact version 5.16.3 (20.12.3)

Ubuntu 21.04 with kubuntu-desktop

Update It seems KOrganier is unable to bring the calendar "online":

Code: Select all

org.kde.pim.davresource: Error when uploading item: 400 "There was a problem with the request. The item has not been created on the server.\nThe file or folder p29-caldav.icloud.com does not exist. (0)."

If I try to refresh the calendar by hitting 'F5', I see:

Code: Select all

If I issue `akondictl stop` and then `akondictl start --verbose` from console, and I open KOrganizer, I only see this:
