Hi Andreas (andreashaerter),
Im also very interested in your workthrough on how to get Roundcube working with the calendar plugin from kolab and CalDAV integration.
In my case I have tried the calendar plugin of Roundcube+, but thats not the same. With their calendar plugin they turn Roundcube itself into a CalDAV server (where external calendar clients can connect to (read/write)). But I only want to connect Roundcube to an external CalDAV calendar, at the side of my mail provider.
So, Im also waiting and will be happy about your recommendations or better a little HowTo, on how to get things working
.
Thanks in advance, Moeppi
