I use Mozilla Thunderbird with Lightnig. I synchronise it with WebCalendar and everything goes just fine. Except when I remove an event in Lightning, it doesn't disappear in WebCalendar, and with the next synchronisation, the event is back in Lightning.
Removing the event in WebCalendar is no problem: it disappears in Lightning as well.
Could someone tell me what I can do about it?
