Hey all,
If you're using Firefox for Outlook webmail, there is a solution posted by RichardAU which I commented on yesterday February 5 and it's very simple to do. I don't think the uBlock Origin extension works in all browsers, but it's worth a try.
I also posted a couple of workarounds for avoiding the copilot draft widget in our emails. Once you hit reply to an email, you can open it in the Drafts folder and compose your email from there without the copilot widget.
I too will be downgrading my subscription to Personal Classic when my renewal comes up in April. It's a little unclear if Classic will eliminate copilot in Outlook webmail, however they put it in there and they're charging for this feature in the other apps, so I'm assuming when I downgrade to the Classic subscription, Outlook will go back to its former operation.
