An OST file is a data file created by Microsoft Outlook (2005 or later), an email client and personal information manager. It is used to store a copy of mailbox information from an Office 365, Exchange, or Outlook.com account. OST files may contain email messages, contacts, tasks, calendar data, and other account information.

OST files are stored on the local computer of a user, which allows the user to access his emails and other mailbox information when he does not have Internet access. Offline folders make it possible for the user to work offline. The user can look up and create appointments, search or add contacts, and read and write emails when offline. However, any changes made offline will not be synchronized with the user account on the server until an Internet connection is re-established.
