Just starting using Outlook 2003.

When composing an email, when go to address the note, it appears that there
are 2 Contact files - 1 is "blank" and the other has lots of my contacts.
It is the latter contact file that I enabled to use as my address book.
Initially address book comes up the first one and I get error message. Then
I toggle to the second one and all the names are accessible.

How do I get rid of the one that appears blank, so only one contact file
appears when I go to address an email?
