Microsoft Teams Essentials subscription

Question

I would like to permanently cancel an old Microsoft Teams Essentials subscription. The subscription is still being billed automatically by Microsoft every month, but I no longer have access to the original business Microsoft account / Microsoft 365 tenant, and I also no longer know the username for that account.

As a result, I am unable to cancel the subscription myself through the Microsoft 365 Admin Center or submit a support request from that account.

I do have the original Microsoft invoice. The identifying details are:

• Product: Microsoft Teams Essentials
• Number of licenses: 1
• Invoice number: [Moderator note: Personally Identifiable Information removed]
• Microsoft order number: [Moderator note: Personally Identifiable Information removed]
• Invoice date: August 18, 2026
• Amount: €4.48 including VAT per month
• Current service period: August 11, 2026 – September 10, 2026

Could you please use the invoice number and Microsoft order number to identify the Microsoft 365 tenant/account associated with this subscription and help me permanently cancel the subscription and stop all future billing?

Answer 1

Dear Remy van Loon,

First of all, I’m sorry you’re having a problem and for the situation you encountered, I deeply understand the inconvenience caused and apologize for it.

As a moderator, I do not have the tools to directly investigate specific user accounts, as this is a user-to-user support platform. Moderators and contributors, including Microsoft contractors, cannot intervene directly in Microsoft product features or access backend systems. Our role is limited to providing technical guidance regarding reported issues, requests, or ideas. However, I will do my best to guide you as clearly as possible.

Since you no longer have access to the original Microsoft 365 tenant and do not know the username associated with the Microsoft Teams Essentials subscription, you will not be able to cancel the subscription through the Microsoft 365 Admin Center yourself.

In this case, I have outlined two specific ways for you to contact the Microsoft Billing Team. They are the only department with the necessary tools to verify your access, investigate your account status, and handle the charge and refund process.

Please help try both options immediately to contact them as soon as possible. This is the best way to ensure your subscription is canceled and that your refund can be processed.

Option 1: Contact Microsoft Data Protection Support by Phone

The most direct method is to call Microsoft's support line to raise a request for cancelling the unexpected subscription. For a full list of regional numbers, you can also visit this official page: Customer service phone numbers - Microsoft Support. The support team will assist you as soon as possible. 

Option 2: Create a Temporary Account (Trial Tenant) to Submit a Support Ticket

If you have difficulty reaching an agent by phone, there is a reliable workaround. This involves creating a new, temporary Microsoft 365 account to contact the support team online. 

• Sign up for a new Microsoft 365 Business trial using this link: Compare All Microsoft 365 Plans.
• Once the trial account is created, log in to its Admin Center. 
• From the Admin Center, open a new Service Request. 
• In the ticket description, explain that you need to cancel the subscription of your primary tenant (your.onmicrosoft.com) and that you need to speak with the Billing team. 
• For reference:  Get support | Microsoft Docs  

Important: Please remember to cancel the trial subscription after your original account issue is resolved to avoid any future charges. 

Once you can reach out to the Billing Team, you can share:

• The exact charge description from your bank or credit‑card statement
• Last 4 digits of the card used
• Invoice number, order number, billing amount, and any other proof of ownership available.
• A screenshot of the charge (optional but helpful)

Contact a Reseller (if applicable): If your Office subscriptions are managed through a federated partner or reseller and the Global Admin cannot open a service request, they should contact the reseller’s support provider. The reseller can assist with initiating the request and coordinating with the Office support team.     

I hope this helps! Please feel free to reply below if you have any update or further concern.  

Your understanding and co-operation are highly appreciated. Thanks for your precious time. Have a nice day!
