The .ost file is the file on your hard disk that contains offline folders. You can create the .ost file automatically when you set up Microsoft Outlook or when you first make a folder available offline. This feature requires you to be using a Microsoft Exchange Server e-mail account.
Outlook automatically determines the format that is used to create the .ost file based on the version of the Microsoft Exchange Server that you are using, the administrator settings, and the formats of the data files that are configured for the profile.
