PST/NSF Elimination
Mailbox quotas often leave users scrambling to find an alternative to message deletion. Many turn to Personal Storage Table files (PSTs) or Notes Storage Format files (NSFs) . This provides end users with the immediate gratification of bypassing quotas and enables them to store content locally. Unfortunately, it also creates immense challenges for IT administrators and legal teams.
Since PSTs and NSFs aren’t typically saved on corporate networks, they pose significant risk and legal exposure. Companies must be able to quickly and easily access this information for legal discovery, regulatory compliance and knowledge management purposes, but they can’t when the files reside in various locations.
Some of the most pressing concerns are around:
E-Discovery: PST and NSF files complicate e-discovery efforts and can lead to serious legal or regulatory problems if organizations cannot find relevant emails when they need them. When IT is asked to search email repositories, they may potentially overlook or never see relevant messages, depending on where they are stored.
Regulatory Compliance: Regulatory requirements are also placing increasing emphasis on the role of email and other electronic content as a source of corporate records. There are a number of regulations, including the Sarbanes-Oxley Act, HIPAA and the Americans with Disabilities Act, that require organizations of all sizes to retain electronic content for long periods of time.
Knowledge Management: It's important for organizations to have complete access to key business information, since it not only helps users do their work, but it also contains records of corporate communications with key clients and business partners as well as other intellectual property. An inability to access these records quickly and easily means that corporate knowledge – the most important single asset that nearly all organizations possess – is simply lost.
