I'm using Outlook Express 6, on winxp sp2 and I received some sort of
incomplete email that I cannot delete.
I see half of the New email msg icon (as opposed to the proper full unread
icon, or the read icon), but there is no sender, subject or receive date.
If i right click on the email, the properties menu item is greyed out. The
delete and move options are available but neither actually do anything.

Right now its quite annoying as this folder shows one unread email and I
can't seem to do anything with it. If I try opening the email I get this
message:
Message could not be displayed
Outlook Express encountered an unexpected problem while displaying this
message. Check your computer for low memory or low disk space and try
again.

but it still shows unread afterwords.
