Messages in your message queue can be viewed in the following locations:
New Messages overlay. The New Messages overlay is similar to the New Messages panel. In addition to displaying your 20 most recent messages, the overlay displays the number of new messages and unread messages, as well as the total number of messages currently in the queue. A View All link is available in the overlay, enabling you to display the Messages page to view all messages in your message queue. Click the New Messages icon in the Icon tool bar.
Messages tab. The Messages navigation tab displays the Messages page, which contains a table of all messages, both read and unread, currently in your message queue. Unlike with the other two methods, the Messages page incorporates a message preview which displays the complete message body.
