It means that you did NOT notify the customer that it was delivered or shipped.
Whenever you want to send info on an order to a customer you need to enter that info in the comments box and give it a Status - then select Notify Customer, and Append Comments. That will send the customer an email of that info and will also post it to his order record.
We use this feature extensively for communication with a customer on an order. We do not send emails outside of the sytem when it relates to an order. This way everyone in the company knows what's up on any given order.
Cheers
