Microsoft Anyone who has ever dealt with Microsoft Outlook will know the .pst file format - it's the binary, undocumented file in which all data from Outlook is stored - emails, contacts, calendar, you name it, it's in there. Microsoft has announced that it will release detailed technical documentation on the Outlook .pst data format.

OSTs are pst format, but the ost signifies that it is an offline copy of what is on your exchange server.
