Hi @james_neill,

Are you saying you only say a first name in the inbox area of Canvas, like the screenshot I'm pasting below?

As you can see in my screenshot, I have first and last names shown there (this is just a testing scenario, so no protected info in that screenshot).  If you're only seeing first names, it could be some kind of local setting or something your school/institution is doing different than we are.  Given that I can see both names, I feel like this is at least not a global issue with Canvas.

Look forward to your response!
