Use Exchange Outlook Global Address Book (GAL) as second address book

Is there a way for a Notes mail client to lookup Exchange Outlook Global Address Book (GAL) as second address book? Another words, is there a way to send an e-mail and when you click on the To: field you can also see the e-mails in Exchange Outlook GAL internet addresses? Currently our users have to use Outlook and look up in the GAL for the internet address and then paste into the Notes mail client.

Or, maybe there is a tool that does an import from GAL to Notes personal address book? Is this possible?
