When trying to mount the public information store it comes up with the following: 'An internal processing error has occured. ID no c1041724'. Event ID 9519 get logged in the event viewer. When you search for these errors it comes up with a permissions issue (we've checked and resolve), then a space issue (we've checked and resolved) and also an AD error (we've checked and can't delete the container). It also won't allow us to do a resotre. Is there any other solution that reloading Exchange?
