title: Accessing Outlook.Application via Python using win32com results in error
body: <p>We have an application which accesses user's outlook account via the following code snippet (see the most upvoted answer):
  <a href="https://stackoverflow.com/questions/5077625/reading-e-mails-from-outlook-with-python-through-mapi">Reading e-mails from Outlook with Python through MAPI</a></p>
  
  <pre><code>import win32com.client
  ...
  outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")
  </code></pre>
  
  <p>It worked fine for several months, alas, a few days ago, it began to fail on all of the organization machines, while returning the following error:
  <strong>AttributeError: 'module' object has no attribute 'CLSIDToClassMap'</strong></p>
  
  <p>The source of the error is:
  WinPython-32bit-3.4.4.2\python-3.4.4\lib\site-packages\win32com\client\gencache.py</p>
  
  <p>I suspect it's related to a security patch applied to Outlook. We use Office 2010 (Outlook 14.0.7173.500 32-bit)</p>
