Accessing Outlook on the web for business using organizational credentials.
Good day Deb, and I appreciate the clear explanation of your concern.
Based on what you described, the issue appears to be that your company domain is currently associated with a Microsoft 365 tenant that you can no longer access.
Just to gently clarify before we go any further, forum users don't have the ability to access, modify, or recover user accounts. Due to security and privacy requirements, issues such as account recovery and releasing a domain that is verified in another Microsoft 365 tenant can only be addressed by Microsoft's dedicated support teams, which have the appropriate tools and authorization to manage account-level settings securely.
If you don't have any other Global Administrators for the original Microsoft 365 tenant, the correct path is to work with Microsoft's Data Protection team. They are the only team authorized to perform identity verification and assist with tenant access recovery or domain release requests.
You can start by calling your regional Microsoft support hotline here: Customer service phone numbers - Microsoft Support
During the phone call, you will need to provide information associated with your subscription, such as your company name, billing details, phone number and an alternate email address. This information enables the Data Protection team to verify your identity and securely assist you in regaining access to your account and releasing the domain.
In some regions, the initial interaction may be automated, so here’s a general idea of how the conversation might go to help you prepare:
Here are some tips and an example of a prompt to help you reach out the Microsoft Data Protection team support more effectively:
(When you call the support number, you may hear an introduction of about 30 seconds such as "you can visit the link...". You can ignore this introduction and wait until you are presented with the options. Then press "1" as a business email user, and again "1" for technical help.)
In some countries, it is an automated conversation like:
IVR: What kind of problem are you concerned about?
You: Lost admin access.
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.
IVR: Do you need a... Service request?
You: Yes. I need to create a ticket. Please send me directly to the Data Protection Team.
- If you cannot reach a live agent by phone, there is still a workaround, you might consider registering for a new tenant by signing up for a trial subscription and submit your request from there.
Here are the reference threads showing that this workaround works:
Note: Although the issue discussed is different (resetting MFA settings for a sole admin), the workaround can help you create a support ticket directly with Microsoft Support.

To set up a new tenant, please follow these steps below:
Visit 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 Data Protection 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 Data Protection team. Here's a message you can use or adapt:
"Hello, I’m currently unable to access my previous Microsoft 365 tenant due to losing admin access. I'm the owner of the business and the domain associated with that tenant, but I'm locked out.
I created this temporary tenant solely to request support. I would appreciate being connected with the Data Protection team so I can complete the required identity verification process and receive assistance in recovering access to my original tenant. I would also like assistance with removing or releasing my domain from the inaccessible tenant so that it can be added to a new Microsoft 365 environment and GoDaddy can proceed with the migration.
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 recovery process."
Ticket Support: In the Microsoft 365 Admin Center > Support > Help & Support. You can raise support ticket at https://admin.microsoft.com/#/support/requests
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
I hope this information is helpful. Even though I can't directly intervene, directing you to the correct and specialized support is the most effective help I can provide from my position.
