I have got 2 yahoo mail emails which will not delete no matter how I try. They appear to delete but I will get a message saying “Message cannot be moved”. I am on iOS 11 on both iPad mini and iPhone 6s.
No, one is a confirmation of an Amazon order and the other is similar from a different supplier. Both companies have sent similar emails which have deleted successfully.
Rather than choosing the delete option could you highlight the email and press DEL on your keyboard.
Or can you foward the email to another email account. Or flag it as SPAM?
Have a look through this Telboy. It hints at compatability issues with ios11 and Yahoo mails amongst others. Having had a quick read through I would try deleting the Y Mails from your Phone and Pad then install the Yahoo mail app from the apple store if you do not already have it.
Attempted all suggestions without success. Can I delete the Yahoo account and then re-install without losing all contacts and email folders and saved messages?
