Address book not showing in Word for envelopes

[twinbytes]

Here's the issue

When going to Word 2010 starting an envelope, we click the Address Book icon to view addresses from Outlook.  It is completely empty.  If we check Outlook, it has all the addresses and works fine.  We just can't see the address book in Word to do envelopes.

Here's what we are using:

• Windows 10 Home 64bit (Brand new computer - 1 week old)
• Office Home and Business 2010

What we've tried with no success.

• We created a new Outlook profile.
• We created a new PST file and imported the address book into that new PST file.
• We tried with Outlook open and closed.

Other software same as previous computer which worked fine.  It never worked on this new computer.  I hope someone has a suggestion that might work?
