Setting the sender email address according to the recipient

Question

How can I set programmatically in an email, to which I reply, the sender address to the recipient address?

Is there a way in VBA? I don't know where to start so I apologize because I cannot show any code.

Credit to @Al Bundy for correcting this. This solution is based on this post.

In ThisOutlookSession:

Option Explicit

Private WithEvents objMail As MailItem
Private assignmentHandled As Boolean

'Set MailItem
Private Sub Application_ItemLoad(ByVal Item As Object)
    If Item.Class = olMail And Not assignmentHandled Then
        Set objMail = Item
    End If
End Sub

'Handle reply/replayAll from triggering ItemLoad again
Private Sub objMail_Open(Cancel As Boolean)
    assignmentHandled = True
End Sub

'Reply
Private Sub objMail_Reply(ByVal Response As Object, Cancel As Boolean)
    Call SetSentOnBehalfOfName(Response)
End Sub

'Reply all
Private Sub objMail_ReplyAll(ByVal Response As Object, Cancel As Boolean)
    Call SetSentOnBehalfOfName(Response)
End Sub

'MailItem closed
Private Sub objMail_Close(Cancel As Boolean)
    assignmentHandled = False
End Sub

' Avoid repeating code
Private Sub SetSentOnBehalfOfName(ByRef Response As Object)
    Response.SentOnBehalfOfName = objMail.To
    assignmentHandled = False
End Sub
