Hi, can anyone report on bynari connector 4 for kolab 3 format: http://bynari.net/de/outlook-connector4-kolab-3-release-notes/ Does it work? With the synckolab thunderbird addon (most recent nightlies) I experience incompatibilities to calendars in roundcube itself. Items synced with kolab3 format in synckolab are not shown! Has anyone else tested this? regards, Henning
