Generating List Of Combinations With Both Unique / Independent And Dependent Input

I coordinate access requests for several contracts, and I have to list the approved accesses in a list where each line represents one person and one contract. For each access request, there will be an arbitrary number of persons obtaining access to an arbitrary number of contracts.

The input would then be as follows: Joe A and Jill B request access to contracts 1001, 1002 and 1003 ->

Joe A   1001
Joe A   1002
Joe A   1003
Jill B     1001
Jill B     1002
Jill B     1003

To automate this task, I have made a simple macro for generating a combination list of all persons having obtained access to a selection of contracts.

My macro worked well when I only wanted to list unique and independent list items, but now I have been asked to include each person's email address. How I can change my code so that only one email address is copied into my list for each person?

Code:
Sub AccessList()
Sheets("requests").Select
Dim rng As Range, c As Range
Dim rng1 As Range, c1 As Range
Dim rng2 As Range, c2 As Range

[Code]....
