I am using the Free for Teachers account. In our district, student's accounts are restricted to emails that are within our domain. For example, trying to add students to my classes, I can add them to the class and send the invitation, but the students are unable to ever receive the message because it comes from outside. This means they cannot confirm their email address and activate their account. I assume I can add them by using an access code, but the students will then be limited notifications only when logged into Canvas. Although our admin could open up student emails to Canvas, they are reluctant (for valid reasons). Is it necessary that students use an email address when they create an account? Is there any workaround other than convincing admin to change policy or asking students to use a non-school domain email?
