Folders Not Appearing in Webmail

Folders Not Appearing in Webmail

Recently I have noticed when I create a new folder in Webmail, it doesn't appear. In fact, only about half of my actual folders do show in webmail. However, when I use Outlook all of them are there and visible. I have tried clearing cookies in the browser. I have tried both in Chrome and Safari (I'm on a Mac Probook Mac OSX) and nothing seems to help. Any fixes would be appreciated. Thank you.
