If I'm reading you right, I think you mean can you see the exact same folders in two separate accounts---------------it that right? If so, I don't think it's possible. You could probably copy all your emails from one Comcast account to another, the same as if it were an external account like Yahoo or Gmail. However, I think it would only work on IMAP folders, and once done, there would be no way to sync them. They are two separate accounts.
