You post is inaccurate. You are not running Outlook 2003 at home, are you?
You are running an older version and PST files from Outlook 2003 are not
compatible with older versions.
This is one of the many reasons why exporting is never the correct way to
transfer Outlook data, as we have posted here countless times.
Instead, you create a PST file in the old format and copy your data into it.
The path is straightforward:
File New Outlook Data File "Outlook 97-2002" Personal Folders file."

At work i exported my outlook contacts to a .pst-file using the export
option. I tried exporting it back in to make sure it worked, it did.
I then took the .pst file home, but here i can't import it!

"The file [filename].pst is not compatible with this version of the
Personal
Folders information service. Contact your administrator."

I'm running Outlook 2003 (I believe that was the version at work as well).
The .pst file contains my phone numbers and contacts so it's important for
me to get it imported back into outlook at home (or at least extracted in
some way). I've noticed a couple of other people with the same problem on
forums, but noone has ever come up with a solution (only on how to import
2003 pst files into older versions).
