Cannot set phishing email as junk

I have been receiving potential phishing emails with "hidden " address like this :

Home Warranty Special
"Covered Repairs On Us + 1st Month Free!"

Outlook won't allow me to mark as Junk because it does not recognize it as valid email address

How do I find the real address of such an email?

Thanks
