This started with one email message stuck in my outbox.  Outlook continues to try to send it, but it won't go.  I have tried deleting it and dragging it into drafts to no avail.  If this is relevant, outbox only shows up in my list of folders briefly, not as a standard folder.  So I have a short window when the folder appears to highlight the email and attempt a delete or move.  Other emails continue to send just fine.  I also tried to copy the body of the email and paste it into a new email and sent it, but now it's also stuck in the outbox.  Any ideas?
