How to send email to undisclosed recipients in Outlook?

When you send an email to a group of friends (some of them are unknown to each other) with putting all of them to the “To” field, it is obviously to expose others email addresses to the unknown people. For keeping recipients email addresses from exposure, you can send them all to the undisclosed recipients and just use the “bcc” field while sending. This tutorial lists all the details of sending email to undisclosed recipients in Outlook.

    I did exactly this in O 2016, and got an error that it does not recognize Undisclosed Recipient, giving me offer to make a new contact, which I did and that brought the same non-result.
