Death to PST Files, A Symantec Hosted Services Whitepaper: “Email is one of your company’s most critical—and most widely used—assets. According to a 2009 study by The Radicati Group, the average corporate email user sends and receives 167 email messages per day. The report estimates that this number will increase to 219 messages per day by 2013. This steady flow of email messages means managing email is more difficult than ever. A company must provide employees constant access to their email accounts and manage copies of every important email to comply with regulatory requirements. If a company is faced with a lawsuit, it must have the ability to easily place legal holds on emails and conduct efficient e-discovery. Since email is the source of so much vital information, users are reluctant to delete old messages, which turns their email system into a personal email filing cabinet. In essence, users create their own email archives using PST files. Most companies impose quotas that limit the amount of storage each person can use for emails. Without these quotas, server disk drives would overflow and email systems would crash.”
