Help Cannot delete emails from my Mail app

[Snakeguy101]

I have checked the settings and I have the "delete from server" box checked and I went onto the server and the emails are not there but when I delete the emails on the app, they will disappear until the next time it refreshes itself. This is getting very annoying and it is crowding my inbox heavily. Anyone else having this problem or know how to fix it?

Anyone?

Me neither. Would really like to be able to delete them from my phone but have not been able to. Even with correct settings. Maybe it's impossible.
