Microsoft made available two new open source projects that complement technical documentation recently released for Outlook Personal Folders (.pst): a “.pst Data Structure View Tool,” is a graphical browser of internal data structures for .pst files that enables a developer to better understand .pst file content. And “.pst File Format Software Development Kit (SDK),” is a cross-platform library that allows developers to read data stored in .pst files and develop apps accessing the data. In near future, the capability to write data to .pst files will be added to the SDK.
“Technical documentation, released in line with Interoperability Principles, makes it easier for developers to read & write data out of .pst files on any platform. Developers previously could access data stored in .pst file format using Messaging Application Programming Interface and Outlook Object Model — a rich set of connections to data stored by Outlook and Exchange Server, available when Outlook is installed on desktop.” The .pst file format documentation reflects feedback from a community of reviewers and is now available here.
