Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello
Nonprofit account is considered "commercial" or "work/school" account by Microsoft's definition, while a personal subscription is on the general consumer side.
Microsoft's commercial and consumer products are from two separate ecosystems, so there is no way to simply do a switch.
You will need to sign up/create the nonprofit account, and then cancel your personal plan via your personal account. Creating one doesn't automatically cancel the other one.
