Entering the subject line while sending mail to any one is one of the etiquette of Email. However it is very common to do this silly mistake. This article will brief you about how to do validation and popup alert message whenever one tries to send email without any subject.
1. Open your Outlook,
2. Press Alt+F11. This opens the Visual Basic Editor and open Project-Project 1 (left side). If this dosen't opens Project-Project 1 then press then Press Ctrl+R.
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
End If
End If
End Sub
6. Now whenever you try to send a mail without subject, a pop-up is raised to remind you of the blank subject.
