Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello Galiryn,
Thank you for coming to the forum and I will be happy to assist with this.
- Click the below link https://account.microsoft.com/services/microsoft365/billing
- Sign in with your Microsoft account email (the one you used for the office 365 subscription or trial)
- There you will see the subscriptions you have
- Select the subscription that you don't want and click cancel (Upgrade or cancel) then follow the prompts to finish the cancellation.
- Please if you have files on OneDrive with this subscription you want to cancel, I will advise you to back them up. OneDrive will not keep the files stored in the cloud for you permanently
See the (reference) link below for guidance on this cancellation process: https://support.office.com/article/46e2634c-c64b-4c65-94b9-2cc9c960e91b
