I'm trying out Canvas with one of my courses this coming fall. I decided to set up all my student accounts prior to the beginning of the semester. When trying to set up "Microsoft Login" it eventually asked me to "verify" the login (followed by a huge login name). To make a long story short, I need to reset/re-create usernames for e-mails already created. I was able to find the method by which I want my students to register, now I just need to fix the 4 students who need to have their login accounts renamed. Ideas?
