Summary


This article describes how to use personal storage folders, also known as .pst files, to back up data that you created in Microsoft Outlook 2010, Microsoft Office Outlook 2007, Microsoft Office Outlook 2003, and Microsoft Office Outlook 2002. You can back up messages, contacts, appointments, tasks, notes, and journal entries in .pst files.

Microsoft Outlook automatically stores messages, contacts, appointments, tasks, notes, and journal entries in one of the following two locations:

  • In a personal storage folder, also known as a .pst file, on your computer.
  • In a mailbox that is located on the server. Your mailbox is located on a server if you use Outlook with Microsoft Exchange Server.

You can use a backup of your .pst file to restore or move your Outlook data if you experience a hardware failure, lose data unexpectedly, have to transfer data from one computer to another computer, or have to transfer data from one hard disk drive to another hard disk drive.
