Windows 10 mail - unblock address

I am trying to unblock a block email address however,

I have searched and the answer is to look under tools / junk email to unblock email address however I cannot find tools icon only settings.

 

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
