auto import and export from outlook

I need to be able to automatically export contacts, tasks and calendar info
from an Outlook 2003 (exchange client) so it can then be imported into a
stand alone remote pc running outlook (pst)

I would like to be able to do all this via command line if possible, but I
am thinking it may need to be a macro driven process.

The goal is to run a script (or macro if necessary) that will export the
info from a specified user on the exchange server then FTP the file somewhere
so it can be downloaded and imported into the remote system on demand.

Any direction on this would be greatly appreciated.
