When you create a quiz using the New Quizzes tool and share it via Canvas Commons or the Send to option and then import the quiz to a Course Shell that has New Quizzes Disabled, you can view/edit/preview the imported quiz (created using New Quizzes) in the course shell that has New Quizzes disabled.

The New Quizzes tool is enabled at a course level, so when a New Quiz is imported into a course shell that has New Quizzes disabled, it should not let the user View/Edit the quiz that is created using the New Quizzes tool. It should display a warning message that this quiz can't be accessed because New Quizzes is disabled in your course.

When the same course does not let the user create a New Quiz if New Quizzes is Disabled at the course level, it should not let the user view/edit the imported New Quiz too.
