I am our institution's Canvas admin and I am trying to figure out how to have student email addresses be displayed in the class list for an instructor in one particular class.
I found this permission that we already have enabled called "Users - view primary email address." Under "What it does" it states, "Allows user to search for other users via primary email addresses in the People page." I tested it and that works. You can indeed search for a student by their email address but only if you know what that email address is! It doesn't actually display the email address on the class list.
If I act as the instructor, I only see the following in the class list:
Name
SIS ID
Section
Role
Last Activity
Total Activity
