Email has become the lifeblood of the modern enterprise: it has supplanted paper-based and verbal communications as the most critical single element of the corporate communications infrastructure. The vast majority of organizations now consider email a viable and trusted medium for taking orders, giving approvals, formalizing contracts and discussing sensitive personnel issues. Consequently, the corporate email system now contains a great deal of sensitive information that once was stored only on paper.
As dependence on email and its use have grown, so has the governmental and legal scrutiny regarding email. Email is now just as admissible in court, and just as critical for an enterprise to maintain, as are its paper-based records.
Complicating the issue is the rapidly increasing volume of email communications and other information contained with the messaging infrastructure. Osterman Research has found that approximately 60 percent of the critical business information that the typical email user requires for his or her job is stored within the email system. Further, email system storage growth increases by 40 percent or more each year because of the growing use of email, increasing use of attachments and increased user reliance on email, among other factors.
