For security reasons, the messaging system allows only three login retries per user session before disconnecting. The messaging system also monitors the number of unsuccessful consecutive login attempts to a specific mailbox across multiple calls to the messaging system. If this number exceeds the number defined on the System- Parameters Features screen, the messaging system locks out that subscriber's login ID, thus preventing further system access. The subscriber cannot access the messaging system until you unlock the subscriber's login.
Use the Edit Subscriber screen, Page 1 to unlock a subscriber's mailbox.
