Jason, thank you for attempting to respond, but the solution to opting out of a "feature" that people don't want shouldn't be to contact Customer Service. This isn't your fault, it's your employer's, but perhaps you should pass these complaints up the chain: lots of people actually enjoy writing things and don't want AI to do it for them (not even if the AI were good at it), and an inexorable invitation to use this "feature" is at best a distraction and at worst a severe annoyance that interferes with getting the writing done at all.
This needs to be something paying customers can opt out of. I understand that Microsoft has a great deal of investment in AI and doesn't want to be left empty-handed the way the company was when it missed the smartphone revolution, but this isn't the way to do it.
I don't want to unsubscribe from Microsoft products--I actually like Microsoft's current products for the most part--but unsubscribing and finding replacements for Office 365 products is ultimately one of the options (and in some cases, e.g. installing OpenOffice, an easier one than dealing with Customer Service). I really hope it doesn't become the choice I'm forced to turn to; like I said, I mostly like Microsoft's products. Copilot has the limitless potential to change my mind on that, I'm afraid.
