My email is POP/SMTP and use Outlook. Does this mean I can't set up new folders on iPhone!All depends on what type of mail system you are using for your mail. If your using Yahoo! or GMail you have full access to your folders from the mail servers. If your using POP/SMTP mail unfortunately you are not going to have access to the mail folders unless your mail is fully hosted on the web as opposed to being downloaded to your computer such as with Window Mail/Outlook, etc.
Unless you open it from safari.
