When you delete a POP3 account from an iOS device, you will lose any mail that’s was stored in the local Sent and Trash folders on the device, as well as mail in the Inbox that has been deleted from the server. Read the information below before deleting accounts in those programs. However, some programs work a little differently.
You can usually delete or replace an email account in these programs without affecting or deleting previously downloaded messages. That said, with many email programs, including Outlook Express, Eudora, and Entourage, deleting a POP3 email account in the program should not delete the messages that have already been retrieved. We can’t emphasize that enough: Always make a backup before deleting anything on your computer or device, because in some cases, your computer or device may have the only copy to start with.
