How Do I Search A Database File??

Hello everyone. I am writing a simple program that takes the records in an MS Access database, and dumps them into the Contacts folder in MS Outlook. The code works fine, but when the user runs the code a 2nd time, it dumps all the records into the folder again, making duplicates. I wanted to know if anyone knew some code I could add to it that would check the contacts folder prior to copying, and would not copy over a name already in the folder. I'm attaching the original code. Any help is greatly appreciated!

Thanks,
