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.

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.

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.

You can upload supplemental files as part of your Conversations messages.

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

You can add a YouTube video in a discussion reply by adding the URL of the video as a link to the response.
