title: Opening files with spaces with outlook.OpenSharedItem is giving error
body: <p>I got the following code:</p>
  
  <pre><code>import win32com.client
  import os
  
  directory = "C:/Users/mypath/"
  for filename in os.listdir(directory):
      _, file_extension = os.path.splitext(filename)
      if file_extension == ".msg":  
          print(filename)
          outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")
          msg = outlook.OpenSharedItem(directory + filename)
          att=msg.Attachments
          for i in att:
              i.SaveAsFile(os.path.join(directory, i.FileName))
          del outlook, msg
  </code></pre>
  
  <p>This code extracts the files attached to a .msg and when I run it, I got the following output:</p>
  
  <blockquote>
    <p>ATP-3770289.msg ATP-5126209.msg ATP-5126317.msg ATT -1937501.msg

  <p>Which is caused obviously because </p>
  
  <blockquote>
    <p>ATT -1937501.msg</p>
  </blockquote>
  
  <p>has a space. I'm running this on Spyder in windows. Any clues how to solve this?
  Thanks.</p>
