You can check this topic and check loop code in your VBA.
The only way around that is going to be to make your object model call from a loop. You will need to continue to retry the call until it succeeds–so you’ll set a success bit right after the call and then have an exception handler that catches (and eats) the 0x800AC472 exception which allows the loopback to continue.
