I need to cancel a trial for Global Microsoft 365 Business Standard

To avoid being charged for the Microsoft 365 Business Standard trial, recurring billing must be turned off or the subscription must be canceled, depending on how it was set up and who billed it.

Because sign-in currently fails with an error, the only way to resolve this is to work directly with Microsoft support or (if applicable) the third party that processed the order.

Use these steps based on how the subscription was purchased:

1. If the trial was started directly in the Microsoft 365 admin center (business trial)
   • The trial is tied to a Microsoft 365 business tenant and billing account.
   • Normally, to cancel a trial before it converts to paid, go to the Microsoft 365 admin center and turn off recurring billing for that trial subscription. The trial then expires at the end of the month and the card is not charged.
   • Since sign-in fails, contact Microsoft support and provide the order number so they can locate the tenant and subscription and either:
     • Turn off recurring billing, or
     • Cancel the subscription in the admin backend.
2. If the subscription is billed under a Microsoft Customer Agreement (MCA)
   • A prorated credit or refund is only available if cancellation happens within seven days after the start or renewal of the subscription.
   • After that window, the correct action is to turn off recurring billing so it does not renew again. Access continues until the end of the current term.
   • Because the admin center is not accessible, support must make these changes on the billing account using the order number.
3. If the subscription is billed under a Microsoft Online Subscription Agreement (MOSA)
   • Canceling after start or renewal typically results in a prorated credit or refund.
   • For subscriptions with 25 or fewer licenses, cancellation is normally done online in the Microsoft 365 admin center; for more than 25 licenses, the license count must be reduced first.
   • Again, with sign-in blocked, support must perform the cancellation.
4. If the subscription was purchased through a partner or third party
   • If the order was placed via a Microsoft representative or reseller partner under an MCA billing account, there is a seven-day window (10 days in Chile) to cancel and receive a prorated refund. In that case, contact the seller or partner directly with the order number.
   • If the subscription was purchased from a retailer (for example, Amazon, Best Buy) or via an app store (Google Play or Apple App Store), cancellation and refund must be handled through that retailer’s or store’s support.
5. If cancellation is blocked or the cancel option is missing
   • When the cancel or recurring billing options are not available online, Microsoft’s guidance is to:
     • Confirm who the subscription was purchased from (Microsoft vs. third party), and
     • Confirm the correct account is being used, and
     • If the issue persists, use Microsoft’s guided support or contact support so an agent can cancel or disable recurring billing on the subscription.
6. Refund eligibility
   • Not all cancellations result in a refund. Refund eligibility is evaluated after the subscription is canceled.
   • For Microsoft 365 subscriptions purchased from Microsoft, the standard process is: cancel first, then check refund eligibility using Microsoft’s refund workflows.

Given the current sign-in error and lack of an IT administrator, the practical next step is:

• Use the order number and contact Microsoft billing/support or, if applicable, the reseller/retailer that issued the order.
• Ask them to locate the Microsoft 365 Business Standard trial associated with that order and either cancel it or turn off recurring billing before the charge date.
