The Inbox is split into two panels and displays messages chronologically. You can view and reply to conversations and sort them by course or inbox type. The Inbox itself does not have any file size limits; however, attachments added to a conversation are included in the sender's personal files.

Notes:

• If you right-click or option-click on the Inbox link, you can open your Inbox in a new browser tab to keep it handy while you are doing other tasks in Canvas.
• Users display in conversations once they have an active enrollment in the course, and users cannot join a course unless it is published.
• Once a course has concluded, you cannot message users in that course.
