How to open OST file without Exchange Server?

OST or Outlook Storage Table files are native to MS Outlook & Exchange Server. OST files are the offline Outlook data files in your MS Outlook that contain information, including calendar data, contacts, email messages, and tasks. It works even in offline or cached mode with MS Exchange.

During a connectivity issue, mailbox changes are stored in an OST file. These changes will synchronize with the server automatically as the connection is restored. Moreover, unlike PST files, these OST files are profile-specific and cannot be accessed without an original profile.

OST files do not usually need to be backed up, but having a back up copy can be helpful in many scenarios.
