Hi! With the new release Support for TBsync was removed or has changed and isn't working. And we really enjoyed the convince of TBsync with Cal- and CardDAV. As we are having our own small Mailserver we already have experience with the Autoconfig XML File. And here comes the real Question: Do you have something similar like Autoconfig but just for the Cal- CardDAV stuff? If not and not even planed please fix TBsync. In case you have something - even if you consider it "Beta" - give it to me, I try any way :).
