After I read an email, my phone keeps if for a day or so, then deletes it. I don't want it to delete any emails without my approval. Why is it doing this and is there something in settings that will prevent it from deleting emails from my phone? I've spent what seems like hours going through the email settings menus and cant' find anything. Is there something in the general settings menu? Please help. I'm running the stock HTC mail program. Thanks.
