O365 / EWS company contact list not shown in emClient

In the contact list screen, emClient is synching and showing my personal Exchange contacts, but there is no option to add the company lists like “All contacts”. So I am missing these contacts here and also when I try to create a calendar entry and try to invite other people.

When I try to show “Public folders” emClient just states, that there are none.

Here is the Outlook online view of the lists, that are not shown in emClient:

Maybe I am doing something wrong, but I don’t find an option to work similar to the Outlook online functionality here because of this.
