Whenever you configure a Microsoft Exchange Server account in your organization, the emails, contacts, calendars and other items of your employee’s mailboxes are delivered and saved on the exchange server. Employees can view their mail using the Outlook Web App (for e.g. https://webmail.microsoft.com/owa) of the server, but the main limitation is that it works only when you have an internet access. Microsoft office provides an option to keep a local copy of your mail items in an outlook data file on your computer. The file is termed as OST (Offline Storage Table). This allows you to work offline even when a connection to your Exchange server may not be possible.
In other terms, you can say that the OST file contains the exact replica of folders as they are on the Exchange server. So you can add, edit or delete the offline folder data as you can do on the exchange server. Whenever the connection between you and exchange server will be established, all the changes will be reflected on the server data also.
