LOss of emails continues even w/ older format. Kept old format worked better for me. Restore or report mechanism needed.
Lost emails since 2017. Lost emails continued after format changes. Kept original format. Since 2019, as I get running out of room messages, now more issues in folders and contents disappearing are unsatisfactory. Since 2020, security issue msgs seem to be more present. What can yahoo do to improve and secure its operations?
We see missing email issues when a mail client such as Outlook is being used. You can submit a mail restore request following the steps here: https://help.yahoo.com/kb/SLN2552.html
