Sent box, junk box, deleted box disappeared

After the latest upgrade to eM Client, my sent box, junk box and deleted box have all disappeared. I have clicked on the More button but nothing there. Please advise.

If the account is setup as IMAP or Exchange, remove the account from eM Client, then add it again.

To see how it is setup, go to Menu > Accounts. It will have either an IMAP or Exchange Web Services tab. If it has a POP3 tab, don’t delete the account.
