Create Outlook PST using script

Does anybody have a script that can do this?

1. execute script from user desktop
2. Ask the user if they want to create a PST
3. If the user selects Yes, then the script will automatically create a PST file and save to a network share and give it a name that consists of the users name.
4. connect the users outlook to the PST the next time they user opens outlook.

We have to create a PST file for ever user for legal purposes and right now the only way I know how is to do it maunally, which I am not looking forward to at all. Thanks in advance for any assistance in this matter.
