[edit] Overview
While in Microsoft Exchange Server, the messages, calendar, and other items are delivered to and stored on the server. In standalone applications (Microsoft Outlook, for example), the messages, calendar, and other items are delivered to and stored locally in a Personal Folders (.pst) file that is located on the computer.

The Personal Storage Table format is supported by several Microsoft client applications including Exchange Client, Windows Messaging, Microsoft Outlook, and Microsoft Office Outlook.
