I have an outlook address book with 199 entries. If I am within the
"contacts" tab, I can use them all effectively.

However, if I am within the message/mail tab and I want to send a message,
clicking on the "To" button brings up a list with only 29 of the names from
the database. I have no idea how to get all of the names from the entire
list to appear as choices.

Do you have any suggestions?
