We often feel horrible when we send email messages to our bosses without any subject line. Here is a simple way to avoid such mistakes...
1. Open your Outlook,
2. Press Alt+F11. This opens the Visual Basic Editor and then Press Ctrl+R which in turn open Project-Project 1 (left side)
3. On the Left Pane, one can see "Microsoft Outlook Objects" or "Project1", expand this. Now one can see the "ThisOutLookSession".
4. Double click on "ThisOutLookSession". It will open up a Code Pane on the right hand side.
5. Copy and Paste the following code in the right pane (Code Pane) and save it
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
6. Save the Project and exit.
Now whenever you try to send a mail without subject, a pop-up is raised to remind you of the blank subject.
