If a course is unpublished, it is inaccessible to students. Publishing your course begins the process of adding students to it. This process can take up to 12 hours. After students are added to a Canvas course, they will have access to the course content.
In Global Navigation, click the Courses link , then click the name of the course .
If your course is currently unpublished, the “Unpublished” button in the Course Status will appear red.
To publish a course, click the “Publish” button in Course Status. The “Publish” button will turn green; the “Unpublished” button will turn from red to gray.
If you need to unpublish your course, click the Unpublished button in Course Status. Students who already received course invitations will not be able to access your course.
Once your course contains a graded submission, you can no longer unpublish your course.
