Whenever new emails are received by your Microsoft Exchange server, Outlook will synchronize your OST file with the Exchange server. It allows you to use the Microsoft Exchange Cached / Offline mode, so you can access your emails without staying connected to your Exchange server. OST files (Offline Outlook Data files): this is the data file format used by Outlook on Windows in conjunction with a Microsoft Exchange account, if you configured Outlook to keep a local copy of your mailbox items. Newer Outlook versions are compatible with this old data file format. PST Outlook data files (97-2002): this PST format does NOT support Unicode characters for your mailbox items and it offers less storage capacity. This data file format is available for all non-Exchange email accounts, such as POP3 or IMAP accounts. The main advantage of a PST file is that you can access your emails offline, without requiring you to be connected to your email server (or to your email server web interface). Outlook PST files are not supposed to be shared or loaded from network locations, as the data loss risk is pretty high. PST files (Personal Folder files): this is the most common format, being used by the Windows version of Outlook 2003 (or newer) to store received, sent & draft emails on your local hard disk. A data file can be located on your local disk or on a network path.

To put it simple, an Outlook data file is a file where Outlook stores your emails, tasks and other Outlook related information.
