So I am somewhat new to dynamics so I was trying out some things.
One of the things I was doing was importing some of the features of the marketing application into another solution. The feature I was trying to add was the marketing email entity.
Testing it out I noticed that the "Test Send" button wasn't working correctly. Instead of bringing up the quick create form it would bring me to this page instead. I tried to fix it manually by adding the needed fields to this "form" to see if I can do something with it. When I try to create something I get this plugin exception.
How would one go about fixing this?
