I struggle to understand how private companies like mine are OK with MS reading all employee email and processing it through their AI. I get these daily creepy emails from MS saying that you said you would do this yesterday.. I have resorted to using burnernote.com, not to hide anything from my company but to hide it from MS who competes with us on some products. I guess burnernote.com will also not work anymore since it creates one-time links. We are monitoring you for your protection.
