My mailbox indicates that I have one unread e-mail. However, there are no unread e-mails in my mailbox. I've completely emptied all the e-mails from my mailbox and the number one is still next to my mailbox. Does anyone have any ideas what this might be? It first occured a couple weeks ago and I hoped it would correct itself when we upgraded from 6.5 to 7 this past monday, but it didn't.
