@bensb You've really got to go down a rabbit hole with MS to see what they're up to, but it appears that they DO collect your data if you've used Copilot. We use MS products at work. Even tho I never activate it and have tried to turn it off, Copilot accessed a Word doc of mine and made unwanted formatting changes to it this week. I never use Word anymore at home.
