How do I send a message to a user in a group in Conversations as an instructor?
In Conversations, you can send a message to one user or multiple users in a group.
Note: Currently you cannot message users in multiple groups.
In Global Navigation, click the Inbox link.
To start a new message, click the Compose icon.
In the Courses drop-down menu, select the Groups option  and then select the name of the group . You can also search for a group in the Groups search field .
To add a user, you can search for the user in the To field  or you can use the Group Roster .
Search for Users
To search for a user, type the user's name in the To field. Canvas will automatically populate matching names. If multiple names appear, use the arrow key to select the user's name. Then press the Enter key. The user's name will appear in the To field, highlighted in light blue. To send a message to multiple users, type the names of additional users in the To field.
If you accidentally select the wrong user, press the Delete key (on a Mac keyboard) or the Backspace key (on a PC keyboard) to remove the user. You can also hover over a user's name and click the white x to remove the user from the list.
Use Group Roster
To select a user from the group roster, click the Address Book icon  next to the To field. From the address book, locate and select the user's name . Names are arranged by last name.
Note: To send a message to multiple users in the course roster, press the command key (Mac) or the control key (Windows) and click the name of each user you'd like to add to your message. Pressing the keyboard key will keep the roster window open.
In the subject line field , enter a subject line for your message.
If you are sending your message to multiple users, but you do not want each user to see who else was included in the message, click the Send an individual message to each recipient checkbox . If your message includes over 100 recipients, this checkbox will be selected by default.
In the message field , type your message. All content is sent in plain text. Note that if you include a URL in your message, the URL will automatically become a clickable link after you send the message.
If you want to include an attachment or media file, click the attachment or media file icons .
When you are finished, click the Send button .
