title: Excel Outlook VBA: DeferredDeliveryTime: Not working
body: <p>I am testing if deferred delivery time works and see that these emails are not sent. I see nothing in the outbox. 
  Emails do get sent if i just .Send and comment out .DeferredDeliveryTime.
  Also, I've tried manually changing Do not deliver before time in Outlook and that does work. 
  So I am not sure what is going wrong here with the VBA.</p>
  
  <pre><code>Option Explicit
  
  Private Sub CommandButton1_Click()
  
  Dim olApp As Outlook.Application
  Dim olMail As Outlook.MailItem
  Dim olAccount As Outlook.Account
  
  Set olApp = New Outlook.Application
  Set olMail = olApp.CreateItem(olMailItem)
  
  With olMail
  
  .To = "my email"
  .Subject = "test"
  .Body = "test"
  
  ' .Send
   .DeferredDeliveryTime = DateAdd("n", 10, Now)
  End With
  
  End Sub
  </code></pre>
