I downgraded my Office 365 Family subscription to Family Classic, although there was no price difference, however Copilot remains in my Outlook Web interface. So that solution did not work for me. I logged out and logged back in again.
I am sick of Microsoft, first it was showing me photos of dead relatives in One Drive's For You feature, that you again can't turn off, second it was my girlfriends laptop last October, trashed by the blank screen desktop bug, thanks to a still unfixed update for Windows (I still haven't found a solution, we had to buy a new laptop), third it was copilot being introduced to my Office apps, with no way to turn it off (at least initially), and now my Outlook web interface has been taken over as well, and despite the solution presented by others here (thank you), it didn't work for me.
Microsoft has become a parody of itself.
"Microsoft 365 (Office) Copilot" - What type of product is that? (Consumer).
It's a software suit of Office applications! (Me)
Why don't they just call it Office? (Consumer)
They did, but now they want people to subscribe to it thinking it's Flight Simulator with an added co-pilot. (Me)
Are you joking? (Consumer)
No. But Microsoft are having a laugh! (me)
*sigh
Solution please Microsoft?
