Just because an email program has been designated the default
does not mean that all protocols have been assigned to it. Do this:
Open the Default Programs applet, which you can access either from
the Start menu or via the Control Panel, then click the first item:
"Set your default programs."
After a few seconds, a list of programs comes up. Click on "Windows
Mail". If it doesn't respond with "This program has all its defaults"
then fix it by clicking on the option indicated by the first green arrow.
