At least one of my folders shows in the left pane that it has one unread message. But in the right pane I have removed all messages. There's nothing there, yet on the left it says I have one unread message. How can I either find the invisible message or clear the warning? In another folder, I do have messages but all are marked as read. But on the left the folder continues to indicate there's one unread message ... somewhere I can't find it. Compacting folders hasn't helped. Any ideas?
