How to Mark a Message as "Read"

Messages do not automatically move from "Read" to "Unread" by opening the message and reading them. The user needs to click the email icon, in order to tell the system that you would like the message moved into your "Read" tab, which is really your Message Archive.

If you hover over the "unread email icon", it will tell you "Mark as Read".  If you click it, then it will move the message from Unread to Read tab.

If you hover over the "read email icon", it will tell you "Mark as Unread".  If you click it, then it will move the message from Read to Unread tab.
