Hi Genius People,

I have designed a VBA code which handles all my outlook outgoing emails.

Currently I am trying to enhance it like: When I will send a Zip/Excel attachment through outlook, my code can able to check and warn whether the attachment is password protected or not.

Please Help.

Check this.

In ThisOutlookSession...

Code:
Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
Dim strCheck As String

Cancel = True

On Error GoTo xEnd
strCheck = CheckAttachmentPassword(Item)

If Len(strCheck) > 0 Then
    If strCheck <> "ERROR" Then
        MsgBox "Following attachments are unprotected." & vbCr & strCheck, vbCritical, "Result"
        Exit Sub
    End If
Else
    Cancel = False
End If

Exit Sub

xEnd:
Err.Clear
Cancel = True
End Sub

In a module...


Code:
Option Explicit

Function CheckAttachmentPassword(ByVal oMail As Object) As String
Dim atmnt As Attachment, oFolder As String, strpath As String, vProtect As String
Dim appXL As Object, oFile As Object, strExt As String, oApp As Object

CheckAttachmentPassword = ""
vProtect = ""
On Error GoTo xError

If oMail.Attachments.Count > 0 Then
oFolder = "c:\temp"
Set appXL = CreateObject("Excel.Application")
Set oApp = CreateObject("Shell.Application")

If Len(Dir(oFolder, vbDirectory)) = 0 Then
    MkDir oFolder
Else
On Error Resume Next
    Kill oFolder & "\*.*"
On Error GoTo 0
End If

    For Each atmnt In oMail.Attachments
        With atmnt
            Randomize
            strpath = .DisplayName
            strExt = Mid(strpath, InStrRev(strpath, ".") + 1)
            strpath = oFolder & "\" & Left(Split(Str(Rnd), ".")(1), 5) & OnlyAlphaNumeric(Replace(strpath, "." & strExt, "")) & "." & strExt
            .SaveAsFile strpath
                Select Case strExt

                        Set oFile = appXL.workbooks.Open(strpath)
                            If oFile.ProtectWindows Or oFile.ProtectStructure Then

                            End If
                        oFile.Close 0

Hi Deepak,

The above code is brilliant at detecting non passworded attachments.. However if an attachment has a password the code opens the application of the attachment and asks for the password. How can we change the code to send the email if the attachment is passworded.

Thanks a lot

I am in a similar situation. Is there any solution to skip the file opening process in case the file is password protected.
