How are you accessing your email? If with a browser and the webmail UI, can you not see the folders in the left pane of the Inbox page?
I can. But spam folder is not listed as a folder. I don't understand it. There are just four folders: inbox, something else, voice, and dialer.
I can't see whatever it is you are looking at, so I'll ask again-------------how are you accessing your email? With only a browser and the webmail UI on a computer, or an email app on a tablet or phone, or a desktop email client like Outlook or Thunderbird?
