In this article "How to create a .pst file in Outlook 2003" you can find how-to create .pst file in different ways.
You can save, copy, and move a .pst file to another location on your hard disk drive, or to a floppy disk or removable disk, or to a share on the network. However, you cannot move the .pst file that is open as your default information store. You must quit Outlook if you want to move your default .pst file.
When you copy a .pst file from a CD-ROM, from a CD-R, or from a CD-RW, make sure that the file attributes for the .pst file are changed from Read Only to Archive before you start Outlook. When you delete items from your Personal Folders in Outlook, the .pst file size does not decrease automatically. The file must be compacted to reduce the file size. Outlook will compact the .pst file in the background during idle time.

When you delete items from your Personal Folders in Outlook, the .pst file size does not decrease automatically. You must compact the file to reduce the file size. To manually compact your Personal Folders, follow these steps:
1. Click Start, point to Settings, and then click Control Panel.
2. Double-click Mail.
3. Click Data Files.
4. Click the .pst file that you want to compress, and then click Settings.
5. Click Compact Now.
Compacting your Personal Folders may take several minutes, depending on the size of your .pst file.
You can select one of three options for encoding the information in your .pst file. You cannot change this setting after the .pst file is created. Encryption encodes the .pst file so that it cannot be read by other programs.
• No Encryption - This option does not encode your .pst file. A user may be able to read the .pst file with a text editor program or with a hexidecimal editor program.
• Compressible Encryption - This option encodes your .pst file in a format that allows compression, but the .pst file is compressed only if you have a compression program on your computer. The .pst file cannot be read with a text editor or with a hexidecimal editor.
• High Encryption - This option encodes your .pst file in a format that offers increased protection. If you have a disk-compression program, the .pst file can be compressed, but to a lesser degree than if you were using the Compressible Encryption option. The .pst file cannot be read with a text editor or with a hexidecimal editor.
The default security setting is the Compressible Encryption option. Use the Compressible Encryption option if disk space is more important than security. If security is more important that disk space, use the High Encryption option, and then select a password for your .pst file.
When you create a .pst file, you can add a password of up to 15 characters. If you click to select the Save this password in your password list check box, note the
password in case you must open the .pst file on another computer.
Repairing Your PST File
To repair your PST file, you'll have to open the Scanpst.exe utility that's included by default with Outlook. The only problem is that there's no shortcut to it, so you'll have to find it in the Outlook folder.
Open up explorer and then browse down to the following folder for Outlook 2007:
C:\Program Files\Microsoft Office\Office12
Or one of these folders for Outlook 2003 and earlier (thanks to Mike in the comments):
C:\Program Files\Common Files\System\Mapi\1033
C:\Program Files\Common Files\System\MSMAPI\1033
