Using classic Outlook for Windows in business environments
Ooops. I guess I spoke too soon. The annoying thing went away for a week, but now it's back, as a little icon at the beginning of each line in Hotmail. There's now a "Copilot" button on the upper right of my Hotmail email screen, but it doesn't allow you to turn it off--only to select it for "Reply" or "Summarize."
Please, Microsoft, listen to the hundreds of people who are sick of this thing and get rid of it!!!!
