I appear to have two accounts and only require one

A Microsoft account can have only one active Microsoft 365 for home subscription associated with it. If the same Microsoft 365 subscription is bought or redeemed again on the same Microsoft account, it normally extends the subscription term for up to 5 years. It does not add extra device sign-ins or extra storage.

To check whether there are actually two different subscriptions or the same subscription renewed/extended:

1. Go to the Services & subscriptions page.
2. Sign in with the Microsoft account used for the Microsoft 365 purchase.
3. Review what is listed:
   • If only one Microsoft 365 subscription appears, the later purchase likely extended the existing subscription.
   • If a second subscription appears under a different Microsoft account, sign in to that account and review it there.
   • If the subscription was purchased through a third-party retailer, selecting Manage can take the account to that retailer’s site for management.

If one subscription is no longer needed, use Manage and cancel the unwanted subscription. If eligible, refund handling depends on where it was purchased. The context also notes that if the purchase was made through a third-party retailer, management is handled through that retailer.

If the issue involves two separate Microsoft accounts and help is needed identifying or cancelling the unwanted subscription, contact support.
