Which of these are not supported by CalDav/CardDav/GroupDav? All open standards and widely supported across platforms. https://tools.ietf.org/html/rfc6638
FWIW, our company recently switched from a self hosted groupware solution to KolabNow - now six months without a hitch, and our ops team able to devote their time to the infrastructure that makes money. With a mix of Windows, Mac and Linux desktops, laptops and servers, it's nice to have a truly cross-platform solution. Some people use Outlook, some Thunderbird, some use the Kolab web UI. I use it with my SailfishOS mobile and Evolution Mail on Linux and love it so far. YMMV.
