How to manage PST file MS Outlook 2003

* Click Start, Settings, then select Control Panel.
* Open User Accounts and double-click on the Mail icon.
* Click the Show Profiles button.
* Select the appropriate mail profile and then click Properties.
* Click the Data Files button.
* Select the Personal Folders Service that you want to back up. By default, this service is called personal folders; however, this service may have been named something else. If there are not any personal folders services in your profile and you have been able to store information such as messages, contacts, or appointments in Outlook, your information is most likely being stored in a mailbox on an Exchange Server.
* Click Open Folder to view the folder containing all of your .pst files and information.
