  • Firstly, temporary changing anything in Outlook does not really work - it will get you no matter what you do. Do your modifications once as soon as you can and do that before Outlook opens it (or it might not see the changes).

    To change the sender, you will need to change a dozen or so PR_SENDER_xyz and PR_SENT_REPRSENTING_xyz MAPI properties (take a look at a message with OutlookSpy - click IMessage button). Note that the Outlook Object Model (being the big brother) won't let you set these properties. You will need Extended MAPI (C++ or Delphi) or Redemption (any language) to do that. The sample script below resets the sender of the currently selected message in Outlook (you can run it from OutlookSpy if you click the Script button and paste the script):

    set Session = CreateObject("Redemption.RDOSession")
    Session.MAPIOBJECT = Application.Session.MAPIOBJECT
    strEntryID = Session.AddressBook.CreateOneOffEntryID("Fake User", "SMTP", "", false, true)
    set addressEntry = Session.AddressBook.GetAddressEntryFromID(strEntryID)
    set Msg = Session.GetMessageFromID(Application.ActiveExplorer.Selection(1).EntryID)
    Msg.Sender = addressEntry
    Msg.SentOnBehalfOf = addressEntry

  • Hello,

    As Dmitry said, Outlook object model does not let us set the sender for a received item. You may use Redemption to get your expected result.

    Here is my test code:

    Dim myMail As MailItem
    Dim myAddressList As AddressList
    Dim myAddressEntry As AddressEntry
    Set myAddressList = Application.GetNamespace("MAPI").AddressLists("Contacts")
    Set myAddressEntry = myAddressList.AddressEntries(1)
    Dim objMsg As Object
    Set objMsg = GetCurrentItem()
    If TypeOf objMsg Is Outlook.MailItem Then
    Set myMail = objMsg
    myMail.Sender = myAddressEntry
    End If
