Imagine a new employee who doesn't just listen to watercooler talk—they can overhear every office conversation, read every scrap of paper left on a desk, and remember it perfectly. If you ask them for the local scoop, they won't just tell you who went to lunch together. They will hand you a copy of the executive salary spreadsheet because someone accidentally left it in an unlocked breakroom cabinet three years ago.
That is exactly how Microsoft 365 Copilot operates. It does not create new security holes; it just listens to what you have already left exposed.
