Submission Comments allows users to view all comments sent and received from assignment submissions. You can reply to submission comments directly from Conversations.

You can also reply to comments directly from assignment submissions. You can evaluate assignments in SpeedGrader and leave feedback for your students, or you can make comments in the Gradebook.

Note: Submission comments only appear between a student and any user who has appropriate Gradebook and SpeedGrader editing and commenting permissions—most commonly an instructor, TA, or both.

You may be able to use Conversations to send a message to all users in a course, all users in a specific role, or all users in a group.

If your recipient list contains more than 100 users, your message will automatically be sent as individual messages to each user.

Notes:

• Messaging all users is a course permission. If you cannot send a message to all users, your institution has restricted this feature.
• Once your course has concluded, you cannot send a message to all users.
• Users display in Conversations once they have an active enrollment in the course, and users cannot join a course unless it is published.

You can record or upload video and audio files as part of your Conversations messages.

For more information about supported uploaded media types, please see the Canvas Media Files lesson.

Note: Attachments appear in your user files in the Conversation Attachments folder and count against the files limit for your account.

In Conversations, you can send a message to one user or multiple users in a course.

Note: Currently you cannot message users in multiple courses.

Conversations is split into two panels and displays messages chronologically. You can view and reply to conversations and sort them by course or inbox type. Conversations 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 Conversation 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.
