title: Extracting text from archived Outlook messages
body: <p>In an Outlook folder, I store hundreds of messages about the status of a battery system. The emails are automatically sent daily. Each message contains information on the battery voltage in the message body, and the information is always formatted as follows,<br>
  DATE: 9/14/2011<br>
  Main Battery Voltage [V]:  25.67    </p>
  
  <p>I would like to write a routine to extract the battery voltage and date information from each message body and concatenate the results so I get a vector of [date, voltage]. I'd like the routine to run from the command line, rather than using Outlook. What is the right tool for this task? Are Outlook messages in a specific folder saved as ASCII files somewhere? If that is the case, I could easily open all the files using perl or similar tool and pull the information out. I just don't know how and where the message body information is stored.</p>
