I set up a rule in Outlook to move messages to a folder. As a test, I set it up to move messages from ME to that folder, and sent myself a message. The folder indicates an unread message - previously the folder was empty - but when I open the folder, my message isn't in there. I try it again. Now the folder shows TWO unread messages, and again, there's nothing in it.

I can't access the message I sent myself. What is going on?
