Thanks for the reply. Its a reagan email and same as on my iPad and MBP. I also have the free iCloud email for the phones iCloud account.
running the latest update ATM.
any email i receive says cannot be moved to trash. now if i send an email to myself , either from the phone itself or off the MBP & iPad , I can delete that. and I've deleted maybe a few others. But 99% of them can't delete.
I did go into edit and then another screen and had to select each one individually,delete , confirm delete, then they would delete from the phone. long process.
Just hitting the trash can doesn't work......
sorry If this is not enough info.
