So my wife just got a new iPad2. She loves it, but mail is behaving unexpectedly. She doesn't remember this happening before, but yesterday she told me that deleting mail wasn't working, that it kept coming back into the inbox. So I did some testing, and the individual emails she was deleting weren't coming back. Rather, once she deleted an email, mail was then loading in an older email. I can only guess that mail wants to keep a certain number of emails in the inbox at all times. Is this correct? It seems weird to me because my iPhone doesn't behave this way. So, first off, can someone confirm that this is normal behavior for mail on the iPad2? Second, if this is normal, is there a way to change a setting so that it doesn't load in older emails after deleting emails in the inbox?
