Copy the .pst file to that PC and configure Outlook to use it.
If you are running Linux there are several open source utilities to convert .pst files to mbox files such as readpst , libpst and Outport . Thunderbird uses a separate mbox file for each folder to store all of the messages for that folder. None of those utilities seem to be under active development and they only support some of the versions of .pst files. You can use the ImportExporttools extension (it used to be called the mboximport extension) to import the mbox files.
