This is only possible with an Outlook/Hotmail account.This may resolve the problem of having emails being deleted, after putting them in created folders. On my ipad 2, I went to settings, then under the email acct., that had the deleting of emails......go to "Mail days to Sync" choice, and choose: NO LIMIT.....You will probably get all "deleted" emails, back into each, created folder. Hoped this helped, cuz it took me a long time to figure it out.......
