Windows 10: Mail 10 will not recognize email addresses

I am trying to send an email to a list of people pasted from a spreadsheet. Each time I hit send, I get an error message say, "Before sending, please remove or correct the following email address" and then names the first address in the bcc field. That email address is correct. If I delete it, I get the same message, only now the "incorrect" email address is the next one. My only options are to "Dismiss" or to keep the email as a draft, but I cannot send it. Help!!

:)

 

Win10 Mail - where's the address book?

That’s now the People app.
If you know the contact's name or email address & they’re listed in the People app, you can start typing the first few letters of their name or email address and Mail for Windows 10 will suggest matching contacts.

 

Mail App: Removing drop down email address suggestions

I'm not a big fan of the MS Mail program and don't really use it for serious stuff but somehow or other if I create a new email then as I start to enter the recipients address a whole load of suggestions will appear. I don't have any contacts in the People app so I'm not sure where these come from.

The question is how can I clear this list so that I no longer get the suggestions?

Thanks
