Excel 2010 :: Get NEW Email On Basis Of Available Email

We know that professional emails have a fixed format. I have a list of people with their names and emails and there are some people for which emails are missing. I am pasting my sample data below. But first let me explain the meaning of columns.

Column A: Means full name of the person for which we have email id
Column B & C: just split of Available full name into first name and last name
Column D: Email id of the person with full name in column A
Column E: For the names in this column, we need to get email ids
Column H: Sample result

Now basis on the Full Name(Column A) and Email Id(Column D) can we get the email id for person in Column E.
