Nokia Mail powered by Yahoo - Why am I getting an authentication error when I run the email setup wizard for Nokia Mail?

When attempting to sign-up for a Nokia Mail account using the E-mail Setup Wizard on a Series 40 (S40) device, the following error may occur when entering an existing Nokia user name and password: An error occurred during login. Please check that your user name and password are correct by entering them in Web Browser (PC).
