How to add people to past courses
If you need to add a user to a past course, you can use these steps to temporarily unlock your course so you can add users. When you manually add the user, they will receive an email invitation to your old course site. After they have accepted the invite**, you can re-lock your course.
** NOTE: If you re-lock the course before they accept the invitation, they will not have access to your course because their enrollment is not complete. They must accept the invitation before you re-lock.
The Unlock Tool temporarily unlocks your course for ONE WEEK. After the week has past, the course will go back to the past courses. You can unlock/re-lock a course as many times as needed.
The Lock/Unlock Tool will only appear in courses that are in a past term.
