Scenario: The sole administrator lost access to the tenant account and is receiving continuous invoice notifications because the trial remains active.

Recover the Admin Account to Cancel the Subscription

Regain access to your admin account using Microsoft Data Protection Support, then cancel the trial directly from the Microsoft 365 admin center.

Microsoft requires administrative access to modify or cancel tenant subscriptions. If you are the only global administrator, you must recover your account before any billing changes can be made.

Initiate Account Recovery

Use the Microsoft account recovery tool or contact Microsoft Data Protection Support to verify your identity and restore access to your tenant administrator account.

Access the Admin Center

Once your access is restored, navigate to the Microsoft 365 admin center and sign in using your recovered administrator credentials.

Locate Your Subscriptions

In the left-hand navigation menu, go to the 'Billing' section and click on 'Your products'.

Cancel the Trial

Find the Microsoft Field Service trial subscription in your list of products, click on it, and select 'Cancel subscription' to stop further invoices.

Recover the Admin Account to Cancel the Subscription

Security Verification: Recovering a sole administrator account requires strict security checks by the Data Protection team, which may take several days to complete.
