We think this problem is caused by using a non-compatible
antivirus program. There is evidence that replacing a non-compatible
antivirus program with a compatible one will reduce the incidence of
this problem. Windows Mail is not compatible with most McAfee or
Norton security programs. Those will need to be uninstalled.
Replace with a more compatible antivirus like the free Avast: http://www.avast.com/eng/avast_4_home.html
As far as the existing stuck message in the Junk E-mail folder,
it is best to just ignore it for now, because the 'fixes' that
are available are complex and not Microsoft approved, nor
do they prevent recurrence.
If the problem becomes worse, or you can't ignore it,
switch to Windows Live Mail: http://get.live.com/betas/maildesktop_betas
