In Global Navigation, click the Inbox link.
If the Inbox link includes a numbered indicator, the indicator shows how many unread messages you have in your Inbox. Once you read the new messages, the indicator will disappear.
View Toolbar
The toolbar includes global message options. To load conversations, filter your messages by course or group [1] and type [2]. Filtering by type lets you filter messages by Inbox, Unread, Starred, Sent, Archived, and Submission Comments. You can compose a message at any time using the compose icon [3].
You can also search for conversations by user in the Search by user field [4].
