Hello @10071 ...
I'm not too sure of an answer for you. Out of curiosity, though...what kinds of data are you looking to get from a one-on-one conversation via the Inbox? Also, are you a Canvas administrator, an instructor, or a student?
Looking forward to hearing back from you soon...take care, stay safe, and be well.

I hope this will help in some way. Sing out if you have any other questions about this...thanks!
