Switching to Microsoft 365 Personal and Family Classic Plans - Microsoft Support
Learn how to switch to a Microsoft 365 subscription plan without AI features, which include Microsoft 365 Basic, Microsoft 365 Personal Classic and Microsoft 365 Family Classic.
Personally I would suggest migrating away from Microsoft 365 by using Libreoffice and Thunerbird or SeaMonkey or your favorite email client rather than giving Microsoft any money. However if for some reason you're absolutely 100% locked-in with Microsoft Office 365 then the linked instructions will at-least save you a little money hopefully. I would still recommend trying to find a solution to why you're locked in as soon as possible because I'm not sure how long this will last.
