End-users often use PST files as personal email archives. They are often scattered across end-user devices and network storage which makes it difficult to find and manage them consistently and effectively. Your users no longer have to save data locally in PST files thanks to Microsoft Exchange and Office 365. You will still need to manage legacy PST files, which contain important data. Barracuda PST Enterprise was created to address this problem. Many terabytes may be stored on PST files on end-user devices or on network servers. These files are notoriously unstable and easy to misplace, and are often corrupted. These large files can be costly in terms of both IT administrative overhead and system resources.
