I have a issue when I’m using Thunderbird and CalDav integration. My calendar is syncing perfect with SOGo. But when I create a calendar invitation and add invitees there is a organisator added who is not me. It is a complete other mail address.
My first idea was a issue in Thunderbird, so I removed and newly installed TB on 3 different machines. On every machine I added CalDav to SOGo in Mailcow. And in every client I have the same issue. So there must be something configured in Mailcow which I cannot change. Also this is not a mailbox configured in Mailcow ..
