Emails go missing on iPad

Q Why are my emails appearing in my ibox but then disappearing before I get chance to read them but appear on my Windows PC in Microsoft Outlook

The answer to you this question is. When you access your POP3 account it pulls all the mail by default from your server inbox. So only the pop3 account has all of your received messages. To prevent this from happening go to Microsoft Outlook.
1. click tools
2. click options
3. click mail setup tab
4. click email accounts
5. click change on your email account
6. click more settings(bottom right)
7. click the advanced tab
8. under delivery CHECK the box that says (Leave a copy of messages on the Server)
9. click OK
Now when you use the pop3 account it should retain them in your iPad.
