Corporate governance and compliance regulations stipulate that information held within corporate messaging systems must be kept for extended periods of time (up to a period of seven years) and must be available for auditing purposes if required. The issue of legal compliance means that email messages and documents not only need to be managed in a controlled infrastructure, but also stored centrally and easily located and accessed for both legal retention and due diligence purposes.
Email systems are becoming clogged up as users retain more and more messages - themselves getting bigger and bigger - adding to the already burdensome list of IT responsibilities.
