Why do I still have duplicates of everything in outlook address book?

[ZPITA]

Some months ago I upgraded my Win 8.1 Surface Pro 3 to Win 10 and decided to start using Microsoft One Drive including my Lumia 950. I had always used POP 3 accounts in Outlook and followed the guidance from this website to establish an Outlook exchange Active x account. This successfully established the email (2) account and things seem to have transferred successfully. While I do not use the email(2) account and it is not my defaut account, it remains in the outlook home screen, which is not just distracting, it appears to somehow get selected as the email account and gets used accidentally. In addition, the contacts and calendar are duplicates. Calendar not so bad, as I can select which one to show and use, but it remains, but the contacts are actively duplicate which is always causing an issue.

How can I eliminate this duplication and suppress the 2nd. email account?

To clarify, I have office installed and am using Outlook, not the mail app. I do not believe the approach suggested will work.

go to mail app, account settings for that email account and look for the section where it says shows contacts - untick that box

To clarify, I an using Office Suite with Outlook 2010, Not the mail app. Do not think this approach works with Outlook. I see the option to choose Calendars, but not Contacts.
