Indicator doesn't show new mail for exchange account

Binary package hint: evolution

New (unread) messages in an exchange account exist, but the messaging menu shows '0' for the message count on the account, and the main messaging-menu indicator icon doesn't indicate anything needing attention.

A notify-old bubble does pop up when the mail comes in, but nothing changes on the messaging menu.
