Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Dear @The Verde Valley Current - Jim Diaz,
Good day, and I appreciate the clear explanation of your concern.
Based on your description, Account B most likely began as a free Microsoft 365 Business trial and automatically converted to a paid subscription when recurring billing was not turned off before the trial ended. This behavior is expected for trial subscriptions unless billing is disabled manually.
Since you do not currently have sign-in information for Account B, the steps below should help you identify the account and proceed with cancellation without affecting your prepaid subscription in Account A.
- Try to identify the admin account for account B
When a Microsoft 365 trial tenant is created, Microsoft automatically assigns a default domain in the format yourdomain.onmicrosoft.com, along with a global admin email address.
Please check the mailbox of the email address you originally used when starting the trial or entering payment details and look for emails from Microsoft that mention “onmicrosoft.com”.
These emails often contain the default admin username or tenant information, which may allow you to sign in and cancel the subscription directly from the Microsoft 365 admin center.
If you are unable to locate this information or cannot sign in, please proceed with one of the options below.
Option 1: Contact Microsoft Billing Support by phone
You can contact Microsoft Global Customer Service by phone to request cancellation of the subscription associated with Account B using the following link: Customer service phone numbers - Microsoft Support
During the call, ask to speak with a live agent and clearly explain your situation. Be sure to mention that you are the only administrator of the account, you have lost access to it and you need assistance canceling the active subscription. This will allow your request to be routed to the appropriate Billing team so the issue can be resolved as efficiently as possible.
Here are some tips and an example of a prompt to help you navigate the IVR more effectively:
In some countries, it is an automated conversation like:
IVR: What kind of problem are you concerned about?
You: Billing.
IVR: What kind of product do you use?
You: Office 365 for business.
IVR confirmation: education or company account?
You: For companies
IVR: Are you an administrator?
You: Yes.
IVR: Do you have another administrator in your organization?
You: No. I need to create a ticket. Please send me direct to the Billing team.
The Billing team will ask for verification details, such as billing emails, company name, payment method, or invoice information, to confirm ownership before canceling the subscription.
Option 2: Create a Temporary Account (Trial Tenant) to Submit a Support Ticket (Alternative Method)
If you still cannot reach to a live agent, there is still a workaround, you might consider registering for a new tenant by signing up for a trial subscription via this link: Microsoft 365 Business Plans and Pricing | Microsoft 365. This would allow you to create a new tenant following the prompts provided. Once set up, you can access the admin console of the new tenant and submit a support ticket requesting to speak with the Billing team on behalf of your previous tenant.
Follow the guided setup process to create a new account for a new tenant.
Once your tenant is created, you should be able to access the support portal and submit your ticket referencing your locked account without further issues
In your ticket description, you'll need to clearly explain that you're trying to regain access to your previous Microsoft 365 tenant and need help from the Billing team. Here's a message you can use or adapt:
"Hello, I am currently unable to access my previous Microsoft 365 tenant, which prevents me from canceling the active subscription associated with that account. I am the only global administrator for the previous tenant and no longer have sign-in access.
I created this new tenant solely to request assistance. I kindly ask to be connected with the Billing team so my identity can be verified and support can be provided to recover access to the original tenant or cancel the subscription as needed.
This is urgent, as I rely on Microsoft 365 for my work and have been unable to operate for several days. I’m available to provide any documentation or verification needed to support the cancelation process."
- Ticket Support: In the Microsoft 365 Admin Center > Support > Help & Support.
- Please remember to cancel the trial subscription after your issue is resolved, as this will help you avoid any accidental billing. You may prefer the following resource for detailed instructions: Cancel your Microsoft business subscription in the Microsoft 365 admin center | Microsoft Learn
