I wrote a Python script to convert a journal file export from Microsoft Outlook to one which can be read by MacJournal.
It requires the Python module csv (included with Python 2.3 or later)
Run the script like so:
./outlook2macjournal.py [input_file] [output_file]
If no input or output files are listed, it will use the following defaults:
Outlook (input): @exchange_export.csv@
MacJournal (output): @macjournal_import.txt@
