A Microsoft offering that enables tracking of cloud usage and expenditures for Azure and other cloud providers.
Hi Mark, here's how to stop it. It takes a few minutes.
First, make sure the bill is real. Don't click links in the email. Open https://portal.azure.com yourself and sign in with the email address the bills are sent to. Also check your bank or card statement for a charge such as "MSFT * AZURE". If you can't find any Azure subscription when you sign in, the emails may be phishing.
To cancel:
1. In the search bar at the top of the Azure portal, type Subscriptions and open it.
2. Select the subscription that's being billed.
3. On the subscription's Overview page, select Cancel subscription and confirm.
To check that it's the right subscription, compare the invoice number from your email with the list under Cost Management + Billing → Invoices:
Billing for usage stops at cancellation. You get one final invoice for anything used up to that day, and the resources are deleted after a retention period.
If you don't see a subscription (because it's under a different sign-in or directory), open Help + support in the portal and create a Billing support request with your invoice number. Billing support is free. I'd also suggest editing your post to remove the invoice number, because it identifies your billing account.
If this stops the billing, please mark it as accepted so others in the same situation can find it.
