There is no function to always add a BCC entry to every email you receive within the interface of Outlook although it can be programmed.
Add the code below to 'ThisOutlookSession' in the VBA console, which can be activated by pressing Alt+11:
Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean) Dim objRecip As Recipient Dim strMsg As String Dim res As Integer Dim strBcc as String ' #### USER OPTIONS #### ' address for Bcc -- must be SMTP address or resolvable ' to a name in the address book strBcc = "[email protected]" On Error Resume Next Set objRecip = Item.Recipients.Add(strBcc) ' handle case of user canceling Outlook security dialog If Err = 287 Then strMsg = "Could not add a Bcc recipient " & _ "because the user said No to the security prompt." & _ " Do you want still to send the message?" res = MsgBox(strMsg, vbYesNo + vbDefaultButton1, _ "Security Prompt Cancelled") If res = vbNo Then Cancel = True Else objRecip.Delete End If Err.Clear Else objRecip.Type = olBCC objRecip.Resolve If Not objRecip.Resolved Then strMsg = "Could not resolve the Bcc recipient. " & _ "Do you want still to send the message?" res = MsgBox(strMsg, vbYesNo + vbDefaultButton1, _ "Could Not Resolve Bcc Recipient") If res = vbNo Then Cancel = True End If End If End If Set objRecip = Nothing End Sub
