Have they been integrated into the new Archive supermailbox? Check your sidebar, should be among the Inbox, Sent, Junk, etc. Also, have you expanded the account structure (the show button, also in the sidebar, when hovering on an account name)? Finally, press Cmd-I and see if the folders are listed in the Quata Limits tab.
