How do I permanently turn off Copilot prompts in my Outlook.com webmail messages?

Solution for current MS365 customers, courtesy of Dwight Silverman, tech columnist at the Houston Chronicle (******@outlook.com):

For those customers on MS365 plans who would prefer not to pay more for something they won’t use, here’s how to revert to the non-Copilot plan and the non-Copilot price. Sign in to your Microsoft account on the web, then click Subscriptions. There, you will see your MS365 account and what you’re currently paying for it. Click on Manage, then click Cancel Subscription. To keep you around, Microsoft will offer other plans, including MS 365 Personal or Family with the word “Classic” added. That’s what you had before, sans Copilot.Oystryk told me there are caveats. Switching to classic is only for current subscribers; newcomers to MS365 can’t get the Copilot-free plans. And if there are any other non-Copilot updates or enhancements, classic subscribers won’t have access to them.

You can't remove it in either version of Outlook..

Having the annoying Copilot banner taking up valuable screen space for every incoming is bad enough, but this draft feature really is the pits. How can I concentrate on what I want to write in a reply if this unbelievably irritating Draft by Copilot image keeps appearing.
Microsoft - have you never heard of usability testing?

This is very useful. I did the whole "threaten to cancel" MS 365 when it comes up for renewal in July and I got to renew at the lower pilot-less price. Unfortunately, this doesn't solve the problem I posted on, which is getting rid of the stupid copilot message in my Hotmail messages.
