How to stop visit notes from being sent to attendees in C4C

Hello,

We want to stop visit notes from being sent (via email as are using Outlook integration) to attendees after check-out but I can't find a way to dos so. I tried to prevent the synchronization of Notes and attachments as mentioned here, but this doesn't work for me:
