Hi Diane,
I found the answer...thank youfor the reply anyway.  I just did not know
where to enable them as Address Books.   It sounds like you are the only
reader who followed the procedure I took to create the 'Subfolders', sorry
for my improper terminology in the original post.

For future users, the following procedure may be helpful.

PROBLEM DESCRIPTION:
When you initiate OUTLOOK, contacts creates a contacts in the contacts tool
bar.
if you highlight it and right click and create'new folder'  for example 'ABC
Co'
it used to create a sub directori/subfolder under/inside 'Contacts'.
So when you were in outlook2000 'MAIL'/ 'new message' and selected 'TO'
button, you could select recipents from the Contacts OR ABCco subfolders.

NOW in Outlook 2003, when I imported the PST file into outlook, it created
10 'subfolders' but now when I select the "TO' button in 'NEW MESSAGE' only
the 'Contacts' is shown not the subfolders...
I know this is a configuration issue but I do not know where or what?

I HAVE FOUND THE SOLUTION!!!!:
ANSWER:
If I right click on a subfolder and go to Properties, there is a 'TAB'
Outlook Address Book. The 'Show this folder as an e-mail address book' option
is unchecked.
IF I ENABLE the 'checkbox', select 'apply', it works....
I guess the imported .PST does not know how to treat the Additional address
books when importing to 2003 or newer outlook options?

Thanks again
Daniel Conn
