Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi,
It sounds like you may have purchased a second Microsoft 365 subscription under a different Microsoft account.
You will need to sign in to the Microsoft account that has the subscription you want to cancel and go to https://account.microsoft.com/services.
Locate the Microsoft 365 subscription, select Manage, then choose Cancel subscription and follow the prompts.
If you are unsure which account was charged, sign in to each Microsoft account and check the Services & subscriptions and Order History pages to identify the active subscription.
Refund eligibility is determined during the cancellation process. If a refund is available, the option will be presented to you. If you do not see a refund option, you may need to contact Microsoft Support:
