Windows 10: 365 Outlook address book

I have two friends with the same email address, whenever I try to email one of them, the other friend's name always appears in the To field. How can I get separate names?

How do I get Outlook 2010 to export the correct address book

I have three options listed in Outlook when I try to export a CSV contact list from the address book.. Myself, another person, and the 'Outlook Data File'. I am the default person.

When you open the address book, the choice that has the current contacts is my name-contacts. When you go to the export file section, it is called suggested contacts. If I export this file and open it in excel, it shows names and street addresses with no email address listed. There are also names in the file that are no longer in my address book.

How do I get the address book to export the current list from my address book, and how do I get the excel file to show the email address?

 

Cannot add contacts personal folders to address book in Outlook 2016

Many thanks for all your suggestions, HippsieGypsie, but nothing seems to be working. I cannot delete my folder so I have to keep trying to get it included in the list of available address books. My contacts are all in the Contacts - Personal Folders, but this list is not included amongst those offered by Outlook as a default address book.
