1. 启动 Outlook，然后按住 ALT + F11 键打开 Microsoft Visual Basic应用程序 窗口。

2。然后，双击 本次展望会议 来自 项目-项目1 窗格，然后将以下代码复制并粘贴到空白代码窗口中：

VBA 代码：阻止外发电子邮件到特定地址

Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
'Updatby ExtendOffice
Dim xMail As Outlook.MailItem
Dim xRecipients As Outlook.Recipients
Dim xContactGroupFound As Boolean
Dim i, n As Long
Dim xRecipient As Outlook.Recipient
Dim xAddress As String
Const PR_SMTP_ADDRESS As String = "http://schemas.microsoft.com/mapi/proptag/0x39FE001E"
On Error Resume Next
If Item.Class <> olMail Then Exit Sub
Set xMail = Item
xContactGroupFound = True
Do While xContactGroupFound = True
  Set xRecipients = xMail.Recipients
  xContactGroupFound = False
  For i = xRecipients.Count To 1 Step -1
    If xRecipients(i).AddressEntry.DisplayType <> olUser Then
      For n = 1 To xRecipients(i).AddressEntry.Members.Count
        If xRecipients(i).AddressEntry.Members.Item(n).DisplayType = olUser Then
          xMail.Recipients.Add (xRecipients(i).AddressEntry.Members.Item(n).Address)
        Else
          xMail.Recipients.Add (xRecipients(i).AddressEntry.Members.Item(n).Name)
          xContactGroupFound = True
        End If
      Next
      xRecipients(i).Delete
    End If
  Next i
  xRecipients.ResolveAll
Loop
For Each xRecipient In xRecipients
  xAddress = xRecipient.PropertyAccessor.GetProperty(PR_SMTP_ADDRESS)
  If VBA.Trim(xAddress) = "" Then
    xAddress = xRecipient.Address
  End If
  If xAddress = "" Then    'change this email address to your need
    If MsgBox("Do you want to email to " & Chr(34) & xAddress & Chr(34) & "?", vbExclamation + vbYesNo, "Kutools for Outlook") = vbNo Then
      xRecipient.Delete
    End If
  End If
Next
If xMail.Recipients.Count = 0 Then
  Cancel = True
End If
End Sub

备注：在上面的代码中，您应该将电子邮件地址更改为您自己的。
