Sincere thanks, Bill. Those are two excellent links, and the second one about archiving helped me understand that feature better (my phone has a swipe to archive feature that I really don't like....)

In the first one about restoring deleted/trashed messages, I note one of the things that cannot be restored,
"Deleted messages from the spam folder." and that is what Glenn told me he did, without thinking about it. He regularly opens the SPAM folder, uses "Select All" and hits "Delete"; then he opens his "TRASH", and empties that, too.

I fear the ball's in Brent's court, to get the software to resend the request for verification, or perhaps to have Glenn open a new account and merge new with old?
