Today I was greeted by 6 ghost emails dated 12/31/1969. I’ve done all the prescribed steps—rebooted mail, hard reset, deactivate-then-reactivate the account in “Accounts and Passwords.” Can’t get rid of them. This has happened before and sometimes the ghost messages disappear by themselves. There has to be a way of disposing of AND preventing them. BTW, this does not happen on my iphone—just my iPad. Suggestions? Thanks in advance.
