I'm am a teacher of a class that requires participation from many other teachers. While entering them into Canvas Module via "+ People", I get a message that indicates that Canvas can't find matches for the email addresses below (see attachment for screen shot). I had this problem on approximately 4 out of 25 email addresses I submitted. I have verified their email addresses and they appear to be correct or at least they work in Google Mail.
Could this have something to do with a mismatch between a Canvas Profile email address and their google account email address?
