I'm using the stock email app, and I let the phone install AOL for me the "automatic" way (where you select AOL from a list of popular email clients and it configures it for you, with the AOL icon and all that). I LOVE this stock email, but no matter what I do, I can't find a way to make the emails delete from the server, when I've deleted them from the phone. It's getting pretty annoying to have to log into AOL from my home PC, just to clean out the mail box. I did try doing a manual install of AOL (so I then lost the custom AOL icon) - but then I stopped getting AOL emails all together.
It appears there is no option to configure email settings when you do the "auto" set up...but surely there must be some other way to have emails deleted from both the phone and the server at once??? Right??
