I had been able to receive and send e-mail messages just fine, but right now
I have one message that won't send. I get a "Windows Mail" window with this
message: "The message could not be sent. An error has occured."

It doesn't tell me what the error is or how to correct it. And when I try
to save and close the message, it just asks me if I want to save it (which I
do, again) and still won't close the window. It doesn't show up in my Outbox
or my Drafts box either.

I turned off McAfee's email scanning, and I've seen suggestions to uninstall
McAfee, but I'm hesitant to do this yet, as this is clearly a "Windows Mail"
error message, not McAfee.

I've seen others with this same problem, but can't seem to find the
solution. Anyone???? TIA for any help!
