Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Sabrina,
Welcome to the Microsoft Q&A forum.
Based on your description, a user in your tenant purchased a Microsoft 365 license/subscription through self-service purchase.
To cancel a subscription purchased through self-service purchase, you can follow these steps:
- In the Microsoft 365 admin center, go to Billing > Your products.
- On the Products tab, select the filter icon, and then select Self-service.
- Select the subscription that you want to cancel.
- On the subscription details page, under Subscriptions and settings, select Take control of this subscription.
- In the details pane, select Cancel subscription.
- Select a reason for cancellation from the drop-down list, and then select Cancel subscription.
- In the Are you sure you want to cancel? dialog box, select Cancel subscription.
- Close the details pane.
- On the subscription details page, the Subscription status will be displayed as Deleted.
If you want to disable the feature that allows users in your tenant to purchase subscriptions themselves, you can follow these steps:
1/ In the Microsoft 365 admin center, go to Settings > Org settings.
2/ On the Services tab of the Org settings page, select Self-service trials and purchases.
3/ The Self-service trials and purchases page lists the products that are eligible for self-service and displays the current self-service setting for each product.
4/ To manage the settings for a specific product, select the product name. A panel will open and display the current settings for the selected product.
5/ To change the product setting, select one of the following options:
- Allow
- Allow for trials only
- Do not allow
6/ If you want to prevent users from purchasing that product themselves, select Do not allow.
7/ Select Save changes.
