Hello @ted Tidmore,
Thank you for providing the details.
The quickest way to resolve this situation would be to check if you can reach the former employee who is currently listed as the Global Administrator. If they are able to sign in and transfer the Global Admin role to you, this can be done immediately in the Microsoft 365 Admin Center and will save time.
However, if contacting the former administrator is not possible, the next step is to work directly with Microsoft Support. For security reasons, only Microsoft can verify ownership and perform an admin reset when no Global Administrator is available. This process cannot be completed through self-service. Please try to find the related hotline number to call the frontline and let them raise a ticket for you: Customer service phone numbers - Microsoft Support
The support agent will then route your case to the appropriate Data Protection/Tenant Recovery team, which specializes in these scenarios.
After your identity and ownership are confirmed, Microsoft will reset the admin access and assign you as the Global Administrator. From there, you can review security settings, add recovery contacts, and proceed with purchasing and assigning Microsoft 365 Business licenses for your users.
Here are some tips and an example of a prompt to help you navigate the IVR 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.
If Support by Phone Is Unreachable:
If you are unable to reach a support agent by phone, there is an alternative approach that can help you resolve your issue quickly. You can register for a trial subscription by signing up through this link: Compare All Microsoft 365 Plans | Microsoft.
Please note that creating a trial tenant is completely free, so you will not incur any charges as long as you cancel the trial after your issue is resolved.
Once your trial tenant is created and registered, log in to the Microsoft 365 Admin Center. From there, select “Help & Support” and submit a support ticket. In your request, please mention that you need to speak with the Data Protection team on behalf of your previous tenant.
This method allows you to connect directly with a support agent through the admin portal and ensures that your request is handled promptly.
Please remember to cancel the trial subscription once your issue is resolved to avoid any unintended charges.
I understand this may feel like an extra step, but it is the most effective way to get assistance when direct phone support is unavailable. If you need any guidance during this process, feel free to reach out, I'm here to help.
