I get what you're saying, but reading these examples has me shaking my head in frustration. The administrator doesn't work in the office. They work in a different office, or from home. Meetings between two higher-ups can't be cancelled because 1. The employee wouldn't even know that a meeting was scheduled and 2. The meeting is scheduled via Outlook and the only way to cancel it would be to have access to your boss's computer while it's unlocked. But supposing you could do these things, and you caused a 2% loss in efficiency by gunking up the keyboard and canceling the meeting. Great, they lost 2% for the day. It's 2% loss of efficiency for people who only work at a 75% efficiency to begin with. They get another keyboard and reschedule the meeting. Tomorrow, you have to start all over again. It won't be long before you're found out. The system is built with these things in mind. The number one security concern in any company is the employees. This is not a new thing and corporations are very good at creating systems of accountability.
