How to turn off or disable no subject warning in Outlook?
When you are using Outlook 2010 and 2013, if you send email messages without subjects, a no subject prompt box will pop up every time for reminding. If you really don’t want to fill in the subject, the no subject warning will be a big trouble for you. For helping Outlook users to get rid of the no subject warning, we provide a skill in the following tutorial.

Turn off or disable no subject warning in Outlook
In Outlook 2007, there is no warning if you send an email message without a subject. This function is enabled in Outlook 2010 and 2013. However, there is no feature for you to directly turn off or disable this no subject warning. In this tutorial, we will show you VBA code for achieving this.
1. Please press "Alt" + "F11" keys to open the "Microsoft Visual Basic for Applications" dialog box.
2. Expand the "Project1" > "Microsoft Outlook Objects" by double-clicking them. And then double-click the "ThisOutlookSession" to open the "VbaProject.OTM" window.
3. Copy and paste the below VBA code into the window.
VBA: Turn off or disable no subject warning
Option Explicit
Private WithEvents oInspectors As Outlook.Inspectors
Private Sub Application_Startup()
Set oInspectors = Outlook.Inspectors
End Sub
Private Sub oInspectors_NewInspector(ByVal Inspector As Inspector)
Dim oItem As Object
On Error GoTo ExitProc
Set oItem = Inspector.CurrentItem
If oItem.Sent = False Then
If oItem.Subject = "" Then oItem.Subject = " "
End If
ExitProc:
Set oItem = Nothing
Set Inspector = Nothing
End Sub
Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
On Error Resume Next
Item.Subject = Trim(Item.Subject)
End Sub
Private Sub Application_Quit()
Set oInspectors = Nothing
End Sub
4. Click "Save" button to save the VBA code.
5. Restart the Outlook application.
Then the VBA code will take effect. When you send a message without a subject, the no subject warning box will not display anymore.
Note: Make sure that the "Enable all macros" option is checked. (Please check it by clicking "File" > "Options" > "Trust Center" > "Trust Center Settings", and in the "Trust Center" dialog, choose "Macro Settings" > "Enable all macros"), see screenshot:
