A visitor to the Microsoft Answers forum asked about forwarding a message and automatically CCing the message to the original recipients. While I would use Reply All and add the new person's address to the message, it is possible to do this using VBA. This quick macro shows how.
You'll need to create a button on the ribbon or QAT for the macro. While you could use a different method and watch for the Forward button to be clicked, that method would hijack all forwards. This method works only on the messages you want to use it on. Note that, as written, this macro will include your address in the message. To avoid this problem, you would need to test the recipients and remove your address.
As always, macro security needs to be set to low.
Open the VBA editor using Alt+F11, right-click on Project1, choose Insert > Module. Paste the code in the new module. Create a ribbon or QAT button for the macro.
Select a message and run the code.
Public Sub ForwardwithCC() Dim strRecip As String Dim objMsg, oMail As MailItem ' For a reply or reply all, replace forward with Reply or ReplyAll Set objMsg = ActiveExplorer.Selection.Item(1).Forward If TypeName(ActiveExplorer.Selection.Item(1)) = "MailItem" Then Set oMail = ActiveExplorer.Selection.Item(1) On Error Resume Next For Each Recipient In oMail.Recipients strRecip = Recipient.Address & ";" & strRecip Next Recipient objMsg.CC = strRecip & ";" & oMail.SenderEmailAddress objMsg.Display Else End If Set objMsg = Nothing End Sub
