Exchange 2003

Would like answers to the following:
1) Is there a tool for recovering a .pst file even if it has been passworded
2) Is there a script that i can use to configure a user’s outlook immediately the user’s log on, instead of going to each client system to configure it
3) How to customize the display name of users using outlook in Active directory so that it would be a combination of first letter of first name plus the surname
4) While creating users using Active directory i want a situation that by the time i press the tab key to go to the display name i want a combinatiion of first letter of first name plus the surname

Thanks
