title: Outlook screen flashing while adding signature
body: <p>I send bulk email to all the staff with default signature in Outlook email. The only problem I am facing is screen flashing. I have used <code>Application.ScreenUpdating = False</code> but it is not working. Please advise as to what could be done.</p>
  
  <pre><code>With OutMail
      .BodyFormat = olFormatHTML
      .Display
  End With
  Signature = OutMail.HTMLBody
  
  On Error Resume Next
  With OutMail
      .To = ws.Cells(I, 4).Value
      .Subject = ws.Cells(I, 1).Value &amp; "-" &amp; ws.Cells(I, 3).Value
      .HTMLBody = StrBody &amp; vbNewLine &amp; RangetoHTML(rng) &amp; vbNewLine &amp; Signature
      .Send
  End With
  </code></pre>
