How do I send a message to a user in a student group in the Inbox as an instructor?
In the Inbox, you can send a message to one user 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. As the sender, you will also be included in the total recipient count.
Notes:
- Currently you cannot message users in multiple groups.
- Once a course has concluded, you cannot message student groups in that course. However, you can still respond to messages from users with the Teacher, TA, and Designer roles in concluded courses.
Open Student Groups

To view student groups in the selected course, click the Address Book icon [1], then click the Student Groups link [2].
Add Users

Select the name of the student you'd like to message [1].
To message all students in the student group, click the All in Student Group link [2].
Send Message

Enter a subject for your message in the Subject field [1].
If you are sending your message to multiple users, but do not want users to see who else was included in the message, click the Send an individual message to each recipient checkbox [2]. If your message includes over 100 recipients (including you as the sender), this checkbox will be selected by default.
Type your message in the Message field [3]. All content is sent in plain text. Any URLs included in your message automatically become clickable after the message is sent.
To add an attachment, click the Attachment icon [4].
To add a media file, click the Media File icon [5].
To send your message, click the Send button [6].
