The Outlook .ost file is an offline data file used by Microsoft Outlook. This file stores all of your Outlook email, contacts, calendar appointments, tasks, notes, and other data. It is created when you set up an Exchange account in Outlook, and is used to synchronize data between your computer and the Exchange server.

The .ost file is stored on your computer, and can be used to access your data even when you are not connected to the Exchange server. This makes it possible to work offline, and then synchronize your changes when you reconnect to the server.

The Outlook .ost file is also used to store a copy of all the data on the Exchange server. This allows Outlook to access the data without having to connect to the server.
