Hi @Elodia Cruz Ortega,
Welcome to Microsoft Q&A forum.
Thank you for reaching out and sharing the details of your situation. I understand your goal is to renew your expired Microsoft 365 Business Basic subscription while keeping the same email address, and I appreciate the steps you’ve already taken to regain access.
You can keep the same email address and domain, but the renewal must happen within the original tenant and be completed by someone with the appropriate admin or billing role. Purchasing a new Business Basic plan from the public signup page - even with the same email - creates a new tenant, which will not reactivate the expired subscription. The person who signs up becomes the admin of that new tenant, so it won’t help with renewing the existing one.
A. How to renew within the same tenant
- Ask the current admin to grant you Billing Administrator (least privilege) or temporarily Global Administrator in the Microsoft 365 Admin Center: Users > Active users > Select your account > Manage roles
- If your organization uses the Microsoft Customer Agreement (MCA) model, you’ll also need a Billing account role (Owner or Contributor) on the billing account to purchase or edit products.
- Once you have the correct permissions:
- Sign in at admin.microsoft.com
- Go to Billing > Your products
- Locate the expired subscription and select Reactivate
B. Fixing payment issues
If your payment cannot be processed, the best next step is to contact the Billing Support team through the Microsoft 365 Admin Center:
1/ Log into admin.microsoft.com with your admin credentials. If you don't have admin permissions, you'll need to contact someone in your organization who does.
2/ Select the green help & support button typically located at the bottom right of the admin center dashboard. Click on it to open the support pane.

3/ Type in “I need to fix payment issue to renew expired license.” into the search bar.
4/ Select “Contact support”.
5/ Choose your preferences: preferred contact method, preferred time zone, and preferred contact language.

6/ Fill in your details and give a strong description of your problem for a quicker resolution. You can add a file, a screenshot, or a video for added support. Once you’ve filled out the details, select Contact me at the bottom.

Once the payment issue is resolved, you can follow Section A to renew your expired license within the same tenant.
