outlook backup

How do I archive or backup my e-mail messages or folders?

Back up Outlook data with the Microsoft Outlook Personal Folders Backup tool.

Export Outlook items to a Personal Folders file (.pst)


  • Each .pst file contains all of your Outlook folders, including the InboxCalendar, and Contacts.
  • Unless you are using a Microsoft Exchange account or an HTTP account, such as Windows Live Mail, all of your Outlook data is saved in a Personal Folders file (.pst). Even when you have an Exchange or Windows Live Mail account, you can back up data to a .pst file, which is saved locally on your computer rather than on the e-mail server.
  • We can have a single .pst file (usually called Personal Folders in our Folder List), but we can also have an additional .pst file that we use for archiving. Using the Personal Folders Backup tool, we can back up any or all of these .pst files.
  • There are three ways to back up your Outlook e-mail messages, contacts, appointments, tasks, notes, and journal entries — the Personal Folders Backup tool, exporting, and archiving.
  1. Personal Folders Backup tool     is used to copy your entire .pst file or files to your hard disk or to a network server or share.
Download the tool from the Microsoft Office Online site by clicking the Download link and following the instructions in the dialog boxes.
To start the setup program, double-click the Pfbackup.exe program file on your hard disk.
Follow the instructions on the screen to complete the installation.
Start Outlook.
