Hi Neon,
This will help show you how to fix the stuck undeletable email message problem in Windows Mail.
The KB941090 update will just fix the problem for now. You must stop the cause to prevent it from happening again. Read the "First" section in this tutorial about antivirus and anti-spyware/adware programs to help prevent this from happening again, then install the KB941090 Microsoft Update in the "Second" section to fix the stuck message problem.
