Hi @rs_1981
@rs_1981 said in Apple Addressbook and Kopano:
Does anyone have an idea, what I can do?
Without any logging its hard to say whats going on. Maybe you can also reach other users of this software through the official github repository at https://github.com/1afa/sabre-zarafa. The last commit to the repository was quite a while ago, but there was some recent activity in a pull request.
Can I also write to the Kopano contacts over sabre or is it an read-only interface?
At least the description does not indicate the opposite.
Is there another way to get the Kopano contacts to Apple OS Sierra?
No, as of yet there is no official support for CardDav in Kopano. The only official client on OS X would be DeskApp. Another community project would be https://github.com/jobisoft/TbSync for Thunderbird, but I don’t know how well it works (the issue tracker makes it seem like it works, though).
