You can unconclude a concluded course. For example, if an instructor has the appropriate permissions to conclude a course before the end of the term, Canvas sets an immediate end date for the course and puts the course in an archived state for both students and instructors. However, as an admin, you can unconclude courses at any time if an instructor needs to have a course restored to the account.
Note: When a course is unconcluded, the course end date and time are automatically removed.
In Global Navigation, click the Admin link , then click the name of the account .
In Course Navigation, click the Courses link.
Note: When you open an account, the account defaults to the Courses page.
