One day I was at work, writing an important email. I inserted the same email address in both “to” and “cc” fields and clicked on “Send” from Microsoft Outlook. Then I realized that I don’t know what happened to my email: did the person mentioned in both “to” and “cc” get no email, one email or 2 identical emails?
I made a quick test and the answer is: the person mentioned in both “to” and “cc” gets one email.
