Does the Unread mail folder say what folder they are in? (click on Arrange
by above the message list and choose Folder to group messages by folder)
If it says Inbox, then a view is hiding them. Click on Arrange by and choose
Date. If you still can't see them, right click on the toolbar area and
choose Advanced. What view is listed in the Current View selector? Select
Messages - if you still can't see the messages, click on Arrange By again
and choose Custom, then Reset.
If it says another folder, then a Rule is moving them - go to Tools, Rules
Wizard and figure out the errant rule.
