VBA code: Get warning when sending email to external domain
Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
'Update by Extendoffice 20180504
Dim xMailItem As Outlook.MailItem
Dim xRecipients As Outlook.Recipients
Dim i As Long
Dim xRecipientAddress As String
Dim xPrompt As String
Dim xYesNo As Integer
Dim xPos As Integer
On Error Resume Next
If Item.Class <> olMail Then Exit Sub
Set xMailItem = Item
Set xRecipients = xMailItem.Recipients
For i = xRecipients.Count To 1 Step -1
xRecipientAddress = xRecipients.Item(i).Address
xPos = InStrRev(LCase(xRecipientAddress), "@addin99.com")
If xPos <= 0 Then Exit For
Cancel = False
Next
If InStrRev(LCase(xRecipientAddress), "@addin99.com") > 0 Then Exit Sub
xPrompt = "Are you sure to send this email to outside your company? "
xYesNo = MsgBox(xPrompt, vbYesNo + vbQuestion, "Kutools for Outlook")
If xYesNo = vbNo Then Cancel = True
End SubNote: In the code, “@addin99.com” is the internal email domain you will send emails to. Please change it as you need.
From now on, when clicking Send button to send emails to external email domain (not the internal email domain you specified in the VBA code), a warning box will pop up as below screenshot shown.
