I have taken a screen shot for you of that message as attached which give me options which is (send) and (don't send) but when i click on any option it brings me back to the same issue. But when I click on the third option (more information) it shows me the attached screen shot. On the other hand, I could access the same e-mail via the web google.com and my I Phone. So, I think the problem on my Outlook itself!

looking forward to your advise.
