iPad deletes messages despite "never" setting
Trying to set up iPad email with Yahoo (Plus) account. Can't get iPad to leave a copy of the messages on the server. 1st set up the email with the "Yahoo!" selection from main host provider menu, no option in that UI to leave a copy on the server. So deleted that account and set it up manually as "other" type of email. Have option selected to never delete emails from incoming server, but they still delete when I download to iPad. iPad problem only... works as expected on iPhone. Any help fixing this is appreciated.
Edit: Tried deleting the email account and re-creating it, but still same problem. Also, this a problem with all accounts/servers, not just the Yahoo server. Set up second email account, same problem. May not be using iPad to check email if this persists (sad). :-(
