Delivery attempted business closed - If the business was closed on the day the package arrived then it would be scanned Business closed. If it is scanned delivery attempted, then the package was attempted and no one was there to receive the package or there wasn’t a secure place to leave the package. At that time a notice is left for the customer to come to the post office and pick it up or to let the post office know they would like redelivery. If there hasn’t been an update, the customer hasn’t gone to the post office to pick up the package and it should still be at the post office.

Delivery attempted will try again - It means USPS will attempt redelivery, usually the next day. Then USPS will leave a notice for you to pick up the package at the post office.
