CardDAV Corporate Directory

Hi,
I would like to use eM Client as my main email client. But the access to our CardDAV corporate directory is not working.

We’re using the Oracle Unified Communications Suite, which provides a corporate directory using the following link: https://carddav.example.com/dav/directory/default/

Which works fine in Apple Contacts (it is even automatically set up when connecting my main addressbook). But I cannot get it to work with eM Client - it always redirects the addressbook to my main personal addressbook (https://carddav.example.com/dav/principals/[email protected]/addressbook/).

Does anyone managed to set up a CardDAV corporate directory in eM Client?

Best regards,
Robin
