thanks for your answer, Vojt=C4=9Bch! Much appreciated.

Running a Radicale Caldav Server. That works like a charm with Thunderbird =
and=20
DavX - Android. Only KDE Kontact gets out of sync. =20

e.g. In Kontact, I accepted an appointment change on Tuesday (it was schedu=
led=20
for 10 am today, postponed to 15:00 today) that came in via mail. The chang=
e=20
is only visible in the one KDE Kontact client that I accepted the change in=
=20
(via mail invite).=20

So this is one client that probably is out of sync, the change never arrive=
d=20
on the server. This works fine with DavX and Thunderbird.=20

What I can reproduce is: Appointments in Thunderbird or DavX are=20
instantaneously written to the server, but not every KDE client does reciev=
e=20
them, even though authentication and all server data are correct. Sometimes=
=20
akonadictl restart helps, but not always and not on all machines. Weird=20

I would love to learn how to debug this in akonadiconsole e.g. =E2=80=93 I'=
m digging=20
deeper here...=20

Once you see something, you can't unsee it.
And once you've seen it, keeping quiet,
saying nothing, becomes as political an act
as speaking out. (Arundhati Roy)
