Problem: Domain / Outlook / autodiscover

I've tried to build several images, but all do fail with domain/outlook. Even images with just unattended and no other things removed/disabled.

1. Installing the image works fine.
2. After that I do install Office 2016.
3. I join domain.
4. Starting Outlook, I do get the message:

the security certificate was issued by a company you have not chosen to trust

Outlook / Exchange do use autodiscover to get user-based cedentials. We do have our own CA.
This problem does not occur with the original, untouched installation image.

Any ideas what to do?
