Dear karnaf,
Sorry for any inconvenience caused to your life.
Please kindly refer to this support article by Microsoft: Switching to Microsoft 365 Personal and Family Classic Plans - Microsoft Support
Since starting from January 16, Microsoft 365 Home or Personal subscriptions will automatically include Copilot, I know this may cause trouble for some users who do not want to use Copilot.
Currently, the option to turn off Copilot is provided in the Office desktop application, but this option has not yet been deployed to Outlook web.
You can refer to the instructions mentioned in the article to switch your subscription to a Microsoft 365 personal/ family classic subscription version without AI.
If you want to better manage your subscription, you can also contact Microsoft's online support dedicated to subscription services: The steps to reach for online support are mentioned in this post Remove Copilot - Microsoft Community
Best Wishes,
