You can filter the conversations in your Inbox for easier organization, especially if you are enrolled in multiple courses. Filtering conversations allows you to selectively view conversation messages by course, inbox, or user.
In Global Navigation, click the Inbox link.
Filter by Course
You can filter your inbox by types of courses. Your Inbox may contain the following options:
Current courses in your Favorites menu 
Other courses that you haven't favorited 
Concluded courses 
Current or concluded groups 
Note: You cannot send messages to users in concluded courses.
Filter by Inbox
You can also filter by Inbox type. By default, the Inbox displays all messages.
The Starred filter displays all starred messages in your Inbox. Starred messages are marked as important so you can locate them later. Learn how to star a message.
View Sent Messages
The Sent filter displays all your sent messages, both to individual users or multiple users.
Note: The Sent filter only includes sent messages from the first user to send a message in a conversation thread. Replies from recipients of the original message will appear in their Inboxes, but not in their Sent filters.
