Can somebody tell me the name and location of the file
that holds the address book? I have reinstall the outlook
and imported the contacts from a comma delimited file, all
of the contacts appear on the contact folder but when I
open a new message window and click on the TO: button to
add recipients a message saying that the address book
could not be found and after that it shows a window asking
for the proper list to show in a drop down list; that drop
down list says 3 times the word "contacts" and if I select
the second then all the contacts would appear but I don't
know who to make it the default option so I can get rid of
the error message.

please help me!!

Thanks in advance for your help!
