Hi,

I currently use Thunderbird with Lighting to connect to a Kerio Connect Server by IMAP and CALDAV. As I found no way to use CARDDAV with Thunderbird to access contacts I want to use Kontact. With Kontact IMAP works (sadly IMAP idle is not supported and only every minute mails get checked, but it works) and CARDDAV works perfectly. My problem is the calendar. I can connect by CALDAV, no errors but no entries added by Thunderbird, Android or the Kerio web client get displayed. When I add an entry with Kontact it gets displayed every where else. So I can't use Kontact How to fix this?

TIA

Solved - finally there is a CARDDAV add on for Thunderbird !

No Need to use Kontact any more.
