To avoid the storage quotas and retention policies that apply to mailboxes on the server, users often create PST files in the Microsoft Outlook client. They can move or copy email from their main mailbox to a PST file on their desktop and keep as much email as they want, as long as they want.
However, PST files cause serious administration and compliance challenges for the organization. PST files increase the possibility of data loss, enable violation of email retention policies and make effective e-discovery nearly impossible—putting the organization at risk of loss of business-critical data and compliance failures that can result in fines and other penalties.
To minimize these risks, organizations are choosing to eliminate PST files and migrate existing PST file data into Exchange or Office 365. This paper explains the best practices for PST file migrations, describes the native tools available, and details how Migration Manager for PSTs can simplify and speed the migration process. It also offers suggestions of additional tools to help you effectively manage your Exchange or Office 365 environment after the migration. Whether you are looking to move PST files to on-premises Exchange or to Office 365, you can take control of PSTs.
