Hello,for some testing purposes I want to subscribe in Thunderbird to the Personal Calendar of the user "sogo2" at the SOGo-demo (demo.sogo.nu, see sogo.nu very below).
There I copied the CalDav URL of that calendar and used it to add a New Calendar ("On the network", ...). The calendar appears in Thunderbird, but it can not be synchronized.
Does anyone have an idea what is wrong here? Best regards Martin -- [email protected] https://inverse.ca/sogo/lists
