In offline (Cached Exchange) mode, Microsoft Outlook stores all Exchange mailbox data in a local file termed OST file. When the Exchange connection is re-established, the modifications made by the user in offline mode are updated to the server mailbox. Exchange Server failures and catastrophes, Exchange mailbox deletions, and other events have no effect on the OST file because it is stored on the user’s PC. As a result, in the case of a disaster, Exchange administrators and end-users can use OST files to restore user mailbox data.

  • A small number of Exchange mailboxes are removed from the server.
  • A couple of Exchange mailboxes need to be backed up. 
  • An Exchange user wishes to rebuild his OST file, however, there is some data in the OST file that has not been preserved.
