Filter settings Outlook and Outlook Web Access (http://mail.letu.edu) have the ability to filter which messages you are viewing. Often when messages seem to disappear, it is because the view is set to filter, so this is a good thing to check if your mails seem to be missing. In Outlook Web Access, look on the toolbar, toward the right side, for a drop-down box labeled 'View.' You'll want to make sure that it is set to Messages. This setting will show you any and all emails in your box.
