Hi, Chris,
Yes, students and instructors can still communicate via their school (or personal) email. But after we've spent a whole semester communicating within Canvas, it's weird and clunky to have to start using a different tool. I know that I really miss being able to stay in touch with my former students via the Canvas inbox, and I know other faculty (and students) do, too.
I'm aware of the Features Ideas forum, but because this is not a new feature, just a former feature that was turned off about a year ago, I didn't think of it as a "feature idea."
Thanks for the links; I will definitely check them out.
Laura
