This probably has happened to each of us, writing an e-mail, then added the recipients and then clicked the send button, and as you clicked it, you notice that you forgot to fill in the subject.
To prevent this from happening, I found the following script today that will bring up an alert when trying to send an e-mail without a subject.
To create the macro in Outlook 2003, go to Tools -> Macro -> Visual Basic Editor (this feature has to be installed). In Microsoft Office Outlook Objects -> ThisOutlookSession, then paste the following code:
Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
Dim strSubject As String
strSubject = Item.Subject
If Len(Trim(strSubject)) = 0 Then
Prompt$ = “Subject is Empty. Are you sure you want to send the Mail?”
If MsgBox(Prompt$, vbYesNo + vbQuestion + vbMsgBoxSetForeground, “Check for Subject”) = vbNo Then
Cancel = True
