iPhone Mail email message cannot me downloaded or deleted
Hi! I want to delete an email message from my iPhone Mail app. I am using IMAP and this message has already been deleted on my MacBook Pro's Mail program. I've also checked my server, but the message is not on my server either.
But for some reason, there it is on my iPhone. When I click on it, I get the error, "this message has not been downloaded from the server". When I try to simply delete it, it appears to go, then poof - the next time I look, it's reappeared.
What's going on and how to do nix this cycle of stubborn invisibility?
iPhone 7 Plus, iOS 11.4.1
