title: Python O365 send email with HTML file
body: <p>I'm using O365 for Python. 
  Sending an email and building the body my using the setBodyHTML() function. However at the present I need to write the actual HTML code inside the function. I don't want to do that. I want to just have python look at an HTML file I saved somewhere and send an email using that file as the body. Is that possible? Or am I confined to copy/pasting my HTML into that function?  I'm using office365 for business. Thanks.</p>
  
  <p>In other words instead of this: <code>msg.setBodyHTML("&lt;h3&gt;Hello&lt;/h3&gt;")</code> I want to be able to do this: <code>msg.setBodyHTML("C:\somemsg.html")</code></p>
