OST File Format Documentation? RRS feed

  • Question

  • I am looking for documentation on Outlook's OST file format. I have found the document at http://msdn.microsoft.com/en-us/library/ff385210.aspx which describes Outlook's PST file format. I wrote some code to read the PST file's header at the binary level, and the code seems to be working. If I run the same code against an OST file, rather than a PST file, there are problems. The header's magic number signatures are not the same.

    Where can I find OST file format documentation?

  • Hi Jeffrey, to reiterate what it states in the thread referenced above, there are currently no plans to publish the OST file format.

    Please let me know if you have any other questions.
