Autoprocess invitations in mailin database

I created a database and made it to a mailin database. This database receives invitations (as FYI). Without any attempt to autoprocess these invitations are stored in my database as documents with form=“Notice” and NoticeType=“I”.

Next target is to have these invitations autoprocessed so that they’ll have form=“Appointment”. I copied the form “Calendar profile” and other design elements (script libraries, folder “Inbox”, view “$Calendar”) from an current mail template into my database and set the autoprocess options in the calendar profile.

However, this seems not to be enough. What does a mailin database need to have to make autoprocessing work?

Kind regards
