Recently, a Texas firm received a dozen Microsoft Outlook .pst files from a client. Like the dog that caught the car, they weren’t sure what to do next. Even out on the prairie, they’d heard of online hosting and e-mail analytics, but worried about the cost. They wondered: Did they really need an e-discovery vendor? Couldn’t they just do it themselves?

As a computer forensic examiner, I blanch at the thought of lawyers harvesting data and processing e-mail in native formats.
