I recently got an email forwarded to me that the sender says he originally sent to another employee. Is there a way I can verify whether he really sent the original email based on the email he forwarded to me?

Hello occs07,

If sender included the full header, then you can tell whether he really sent or not sent the email.

Hope this helps!

Sender did not include full header. This person says that he sent an email to an employee but the employee swears up and down he never got it.

You need to look at the sender's computer and find the email and the header. That's the only way you can tell if sender really sent the message.

Because I am unable to access the users computer that sent the original email, I am unable to authenticate the validity of the email in question.
