Exchange Admins?

Guess I’ll be more specific with my technical ramblings.

Any Exchange administrators in the house?

If so, answer me this:

What is the simplest way to merge two public folder address books in Exchange 2007, such that an end user wouldn’t need to manually add 2000 some odd addresses to a new address book, checking for existing duplicates, etc.

Easy way to do this?

Isn’t there an export function in exchange? That allows you to export to even a CSV file and then you can just import back into the desired location? Unless there are errors in the export there should be no hick-ups cross your fingers and knock on wood.

there certainly is client-side, so I was hoping there was something on the server side that operates the same way…the last exchange environment I worked with was pre-2000 so i’m a little out of the loop
