If this topic has been covered before I apologize. I have a proximately 4000 emails on my Iphone 7 and would like to erase them one good time versus one by one can anyone help?
In the Inbox, tap Edit at the top right. Mark one email. Then tap and hold Move at the bottom. While still holding it, unmark the email, then lift your finger from Move as well. That done, you’ll see how many emails will be moved at once, and where it’s possible to move them.
