OE removed access to the following unsafe attachments in your mail
If receive this error with attachments in Outlook Express, here's how you fix it:
Outlook Express 6 has quite a few security enhancements that are good, but with
some of the latest security patches OE has become so hyperactive with blocking
everything that even having an attachment has become useless.
To view the attachments that Outlook Express has deemed "unsafe" do
Open Outlook Express
Click the Security tab
Uncheck the Do not allow attachments to be saved or opened that could potentially be a virus box
If you're opening an executable, be absolutely sure that it's safe. I never
open an exe unless I know exactly what it is, and was expecting it.
