You can use the BlackBerry® Message Receipt Confirmation Tool (MessageConfirmService.exe) to verify that the BlackBerry® Enterprise Server is sending messages to BlackBerry devices.

Each time the tool starts, it clears the existing message delivery status values. The tool obtains the list of user accounts to monitor and sends a message to the BlackBerry device that is associated with each user account.
The tool assigns a serial number to each message and then increments the serial number by 1 each time it resends the message.
When the tool reaches the interval value that is specified in the Last Message Delivery Check field, it checks whether the messages were successfully delivered and updates the Last Message Sent field, the Serial Number field, and the Deliveries list.
If the tool reaches the value that is specified in the Delivery Timeout Interval field, a timeout status message for the user account displays in the Deliveries list, and the tool sends a delivery timeout notification message to the defined SMTP email account to indicate that the message was not succesfully delivered.
