Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
To cancel a Microsoft 365 subscription for home immediately, use the Services & subscriptions page for the same Microsoft account that was used to purchase the subscription.
- Go to the Services & subscriptions page at https://account.microsoft.com/services and sign in with the Microsoft account that owns the subscription.
- Under Services & subscriptions, locate the Microsoft 365 subscription that should be canceled.
- Select Manage next to that subscription.
- If recurring billing is on, select Cancel subscription (it might appear as Upgrade or Cancel) and follow the prompts to confirm cancellation.
- If instead of Cancel subscription there is a Turn on recurring billing link, the subscription is already set to expire on the date shown and no further charges will occur; it can be used until it expires.
- If the subscription was purchased with recurring billing through a third-party retailer (such as Amazon, Best Buy, or a mobile app store), contact that retailer directly to cancel and manage billing.
After cancellation of a Microsoft 365 Basic, Personal, Family, or Premium subscription, the storage allowance reverts to the free level (5 GB of cloud storage plus 15 GB Outlook.com storage). If more than the free allowance is in use, uploading or syncing new OneDrive files and sending or receiving Outlook.com email will be blocked, and OneDrive content may be deleted after a period of time.
