This article is written for the Microsoft Outlook Personal Folders Backup tool that is available as a download from Microsoft Office Online.

The Personal Folders Backup tool is designed for use in Outlook 2002 and later and the operating systems that support each respective Outlook version. The tool provides a quick and easy way to back up the Outlook information of your choice to your hard disk or network server or share.

After you back up your information, you can copy these duplicates of your Outlook data to a removable media such as a CD or DVD. The backup files are exact copies of the original files and are saved in the same file format. You can receive periodic reminders to back up your files.

About Personal Folders files (.pst)

Unless you are using a Microsoft Exchange Server e-mail account or an HTTP account, such as MSN® Hotmail®, all of your Outlook data is stored in a Personal Folders file (.pst) (Personal Folders file (.pst): Data file that stores your messages and other items on your computer. You can assign a .pst file to be the default delivery location for e-mail messages. You can use a .pst to organize and back up items for safekeeping.). Even when you have a Microsoft Exchange Server or Hotmail account, you can back up data to a .pst file, which is stored locally on your computer rather than on the e-mail server.

Each .pst file contains all of your Outlook folders, including the Inbox, Calendar, and Contacts. You can have a single .pst file (usually called Personal Folders in your Folder List (Folder List: Displays the folders available in your mailbox. To view subfolders, click the plus sign (+) next to the folder. If the Folder List is not visible, on the Go menu, click Folder List.)), but you can also have an additional .pst file that you use for archiving.

* Personal Folders Backup tool only backs up .pst files. If you have an Exchange Server mailbox (mailbox: Location on a Microsoft Exchange server where your e-mail is delivered. Your administrator sets up a mailbox for each user. If you designate a personal folder file as your e-mail delivery location, messages are routed to it from your mailbox.), your server mailbox folders should be backed up regularly by your Exchange Server administrator.
* If you are using an East Asian operating system with an English version of Microsoft Office, you cannot use this download.
