• Answer:

  Do you actually have a "plus" account, or are you just entering the plus settings while using a regular account. Yahoo Mail Plus is a PAID service @ $19.99 per year. You can upgrade from your regular FREE account by clicking Options > Mail Plus > Upgrade Now > enter your payment card information for the required fee and complete the transaction.
