I'm having a problem and I wonder if you have gone through this. The employees here in the company are claiming that the quota is running out of them without them use. And this is really happening. The configuration of my quota rule conforms the library web gateway, the only difference is the creation of whitelist certain sites as print.
I created a rule that warns me of sites that are going through the quota rule, but when I ask for the users tell me that they are not using the quota, as if he had left without permission.
I was with version 7.2.xe I upgraded to version 7.3 thinking that this could solve, but nothing.
