I tried to reply to a student's IM message (they are in my course) and got the error "... only accepts messages from their contacts", even though I'd replied to their message previously. I added them to my contacts by following the instructions here (https://it.umn.edu/moodle-32-add-contact-your-moodle) but I'm still getting the same error. Any idea what's going on?
Error message = ... only accepts messages from their contacts.
Possibly the student you are getting the error from needs to click on their name at the top right and select, Preferences. On the Preferences page, they need to select, Message preferences. On the resulting page, they need to REMOVE the checkmark in the the Prevent non-contacts from messaging me.
