Adding New Users

Is there any way to manually add new users to the help desk from AD without overwriting everything, The problem we have is we have recently had several new teachers that need access to the helpdesk i would like them to use domain authentication instead of local and log on using there Domian name + Password.

I have manually updated all the email addresses, phone numbers, department etc for the requesters on service desk, However the user details in the AD do not include these details. How can i add the new users without inturn deleting all the email addresses, department etc that i have already manually added in the helpdesk

I know the obvious answer is Add the details to the AD, but it will take along time to manually update all the users, Unless anyone knows of a way to export the AD to CSV then Import it back in with the changes?

Any help greatly appriciated
