The simple way to restore .pst files in outlook is

Choose Export to a file
Choose Personal Folder File (.pst)
Select the Inbox and press Next (we do the Contacts folder later)
Set the file location to D:\My Documents\My Outlook\Backup\export.pst
Press Finish and you’ll be prompted to set properties for the export.pst file
In the Name field type a descriptive name like "Export June 2004" (yeah, I wrote this guide a long time ago but don’t worry; I still keep it up to date!)
Press OK to start the export
To export the Contacts folder as well repeat step 1 to 4 and this time select the Contacts folder
If the save location is not set to the path you’ve set in step 5 browse to it
Press Finish to export the Contact folder
Close Outlook and copy the exported file to your safe location as described in Backup pst-file

I dunno but you might be better off just copying the outlook express data files from one computer to the next instead of trying to export.

from the horses mouth.

Have a look at this follow the instructions it should make it all better.

MailNavigator can cope with the task of restoring out-of-order dbx files when Outlook Express itself cannot read them and when a range of other programs are not capable of restoring the information contained in these files. These situations can happen because of viruses, computer breakdown, power interruptions and many other reasons, leading to errors in the file system.
If your computer crashed, first of all you should make sure you have backup copies of your dbx files as well as of all other important data. It's good if you make backup copies of your data on a regular basis. But, unfortunately, in our experience situations are often encountered where there is already nothing to restore.
The process of data recovery from dbx files includes two stages:

• Search and read the dbx files in MailNavigator.
  
• Export the restored messages back to Outlook Express.
  

If your Outlook Express program is properly installed and tuned, MailNavigator will automatically find the dbx files from the information in the systems register. In this case you can load the dbx files from the Information Retrieval page by double clicking on each of them. Or search for messages in these files using the search system.
If MailNavigator cannot automatically determine the location of the dbx files (for example if these files are on a CD), first you have to find them using search tools, and then load them into MailNavigator using the menu command:
File | Load External Mailbox...
Once you've read the messages, select the ones that should be exported back into Outlook Express. You can use various filters to select the messages. If you want to export all the messages browsable in the Navigator at once, use the menu command:

Message | Select All
Having selected the messages, export them using the menu command:

Message | Save as...
In the opened dialogue box, indicate the file and export path, and choose the file type: Eudora mailbox.
When the command is executed, there will be files in the export directory with extensions .toc and .mbx, and also a file descmap.pce. If there are attached files in the exported messages they will be saved in the subdirectory Attach.


Once the mailbox in Eudora format is created, open the program Outlook Express and use the menu command:
File | Import | Messages...

In the opened dialogue box, as the program from which the message is imported, select: Eudora Pro or Light:

In the next dialogue box indicate the directory in which you put the messages from MailNavigator at the export stage:

Further, if Outlook Express finds mailboxes in this directory, it will suggest you select one of them for import:

All that remains to do is to press the Finish button, and a folder containing the imported messages is created in Outlook Express. hope this helps
