title: Apache Tika - not indexing email attachments
body: <p>I am using Apache Jackrabbit 2.6.0 as my document management system. </p>
  
  <p>When I upload email type of document with attachment, it index the email content properly. However, it doesn't index content of attachment. </p>
  
  <p>I went through source code of Jackrabbit &amp; while debugging observed that it uses Apache Tika to extract text from binary files like office documents (msg, docx etc...). It seems, OutlookExtractor.java is unable to identify correct parser for attachment type of document. </p>
  
  <p>I am using default config in tika-config.xml (it's used by repository.xml of jackrabbit). </p>
  
  <p>Please let me know in case of any tips or direction from anyone. Am I missing anything specific to email &amp; attachment in tika-config ?</p>
