Attempting to manage today's email systems is one of the most challenging and important IT jobs today. According to a 2003 IDC survey, 97 percent of email administrator respondents said their email stores grew faster than predicted. Email is growing in volume (number of messages sent), as is the size of each email.

According to IDC, an average corporate user sends or receives 120 emails per day. Add to this, a 35 percent compound annual growth rate of each email size (growing from 1-3 KB in the early 1990s to more than 5 KB today - with 20 percent of emails containing attachments averaging more than 100 KB).

Furthermore, with the surge of email growth, users are demanding 24/7 email availability. For most organizations, email is not only mission-critical, it is the gateway to corporate decision making, accountability, and revenue.

Combining the growing volumes of email with the absolute demand for round-the-clock availability, email administrators are forced to create policies that are frequently ineffective, such as creating size limits/quotas for individual message stores. According to IDC, the corporate user will exceed their message store in 16 days. Moreover, to circumvent these policies, users store their email in multiple places (network drives, laptop hard drives, etc.) and in multiple formats (pst files, text files, etc.).

These policies, combined with email growth and users availability requirements are producing inefficient, expensive storage management, complex email administration, and difficulty with regulatory compliance. Clearly, effectively managing email systems is a massive challenge.

From lost revenue to ineffective email policies, the problems associated with managing email systems have far reaching implications in both time and resources.
