Hello Diane,
 I asked the same day the same question in the Q&A forum - but nobody answers. Is here really nobody, who can answer what the Note means?

Are you only sending mail to internal addresses?

Because this forum is targeted to end-users, not admin or Microsoft 365 development issues, and although some of us can answer some of these questions, the new Q&A forums are better suited for these questions. They should be able to tell you how to do what you want.

Unfortunately, moderators are unable to move messages to that forum, so you'll need to repost it.
