How do I use the Inbox as an observer?
The Inbox is split into two panels and displays messages chronologically. You can view and reply to conversations and sort them by course or inbox type. The Inbox itself does not have any file size limits; however, attachments added to a conversation are included in the sender's personal files.
- Users display in the Inbox once they have an active enrollment in the course, and users cannot join a course unless it is published.
- Once a course has concluded, you cannot message users in that course.
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.
The toolbar includes global message options. To load conversations, filter your messages by course or group  and type .
You can also search for conversations by user in the Search by user field .
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 button .
Conversations for your selected course and Inbox filter appear in the left Inbox panel.
The Inbox is organized chronologically from newest to oldest with the newest conversations appearing on top  and the older conversations at the bottom.
You can manually mark a conversation as read or unread by hovering over the conversation and clicking the circle to the left of the conversation . To star a conversation, hover over the conversation and click the star to the right of the conversation .
When you select a conversation , all messages in the conversations thread appear in the right Inbox panel .
To select multiple messages to archive, delete, mark as read, mark as unread, or star, click the checkbox for each message . You can also press the command key (Mac) or the control key (Windows) while clicking each message you want to select. In the Inbox toolbar , click the desired option.
To select all messages, click the command + A keys (Mac) or the control + A keys (Windows).
To select a range of messages, click the first message you want to select, hold down the Shift key, and then click the last message you want to select. All messages between the first and the last messages will be selected.
Note: You can also click the message check box or use the same keyboard command to deselect a message.
