First and foremost, this isn't the first problem I've had with emails that won't delete, but it's always gone away after a day or so of deleting it repeatedly, and this time, it hasn't.
The biggest issue as of current is that the email display date is 12/31/1969. If I try to sort my emails by date, it always appears at the bottom, saying it was sent in 1969. I try to delete it, refresh my inbox and it reappears. I've tried to quickly clear out my Trash folder, but somehow, the email always sneaks back into my inbox. If there are three messages -including the one that won't delete- my Trash will say there are only two emails in the folder. I tried that Yahoo mail fix tool and it came back saying they couldn't find any issues. I don't know how an email registering from the 60s wasn't a red flag, but okay. The troubleshooter came back and said use a different computer with a different browser, clear your cache and try again. Done, done, and done. So far, I've used three computers, one phone, each with a different browser and zero joy.
Any help would be appreciated in fixing this aggravating issue.
