如何阻止外發電子郵件到 Outlook 中的特定地址？

一般來說，Outlook 會向所有正常的電子郵件地址發送電子郵件，並且無法阻止向特定電子郵件地址發送電子郵件。但是，有時，您可能需要阻止將電子郵件發送到 Outlook 中的特定電子郵件地址。在這種情況下，本教程將介紹用於解決此任務的 VBA 代碼。

使用 VBA 代碼阻止外發電子郵件到特定地址

下面的 VBA 代碼可以幫你一個忙，請這樣做：

1. 啟動 Outlook，然後按住 ALT + F11 鍵打開 Microsoft Visual Basic for Applications 窗口。

2。然後，雙擊 本次展望會議 來自 項目-項目1 窗格，然後將以下代碼複製並粘貼到空白代碼窗口中：

VBA 代碼：阻止外發電子郵件到特定地址

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

備註：在上面的代碼中，您應該將電子郵件地址更改為您自己的。
