URGENT: Sole Global Administrator locked out, Microsoft 365 Business support channels unavailable in Australia

Amy 0

I am the sole owner and sole Global Administrator of a new Microsoft 365 Business Standard tenant.

After changing my Microsoft account security information, I am locked out for 30 days. There is no second administrator who can restore access.

I have followed Microsoft's recommended workaround and created a temporary Microsoft 365 trial tenant so I can access the Admin Centre and contact support.

However, the Admin Centre Contact Support function only provides the Australian telephone number 1800 197 503, which is disconnected.

I have also tried Microsoft's published Australian business support number 13 20 58, plus multiple other Microsoft support routes, without being able to create a support case or reach an agent.

My phone number is already correctly registered in my Microsoft 365 admin profile.

I need Microsoft assistance to:

Identify my original Microsoft 365 Business Standard tenant.
Verify that I am the tenant/subscription owner.
Restore access to my sole Global Administrator account.
Escalate this to the Data Protection / Tenant Recovery team if required.

I can provide proof of purchase, billing information, identity and proof of ownership of my business domain amy***.com.au** privately.

Please do not ask me to reset the account through another Global Administrator. There is no other administrator.

This is preventing me from setting up and operating my new Australian business. I need assistance obtaining a Microsoft support case number or escalation to the appropriate recovery team.

Dear Amy,

If the Australian support phone number does not work, please try the English-language support number.

Additionally, could you please let me know how you created the trial tenant? Kindly repeat the process by following the steps provided below to raise a ticket. As this issue relates to tenant account recovery, only the Data Protection team is able to assist you in regaining access.

To set up a new tenant, please follow these steps:

Visit Compare Office 365 Enterprise Pricing and Plans | Microsoft 365, choose any plan and click try for free to start a free trial.

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 the ticket's description, you could refer to this message

"Hello, I am currently locked out of my tenant because multi-factor authentication is enforced, and I am unable to complete the verification process. I am the only global administrator for this tenant, which means I cannot access my account or the Microsoft 365 Admin Center. To resolve this, I have created a new tenant and would like to be connected with the Data Protection Team to verify my identity and assist with regaining access. I am available to provide any required documentation or verification to support the recovery process."

Ticket Support: Log in the Microsoft 365 Admin Center using the newly created trial admin account (not the currently locked one) > Support > Help & Support. You can raise support ticket at: https://admin.microsoft.com/#/support/requests

When you open a support ticket, please make sure to turn off the Support Assistant (AI) in the help panel.

Several customers have reported issues when the Support Assistant is turned on the system sometimes fails to display the “Contact Support” option.

As shown in the screenshot, simply switch Support Assistant > Off, then type your issue description. Once the AI is off, the “Contact Support” button will appear normally, allowing you to submit a ticket directly.

After clicking on "Help & Support" button, you can type "I need agent support via phone or email". After that, you can click on "Contact support"

Choose contact method: "Phone"

Fill all the information in this contact support details, please describe your situation carefully so they will have enough information to help you.

Finally, click on "Contact me"

After completing them, you will receive an email appointment for a meeting to review this issue professionally together.

For more details, you could refer to this article: Get support for Microsoft 365 for business

Please remember to cancel the trial subscription once your issue is resolved to avoid any unintended charges.

Thank you for your kindness and patience!

Did you get the license from a reseller? The reseller often has a back channel via their distributors to also assist.

Typically if the phone lines don't work for whatever reason, the other alternative is to raise a support ticket via web, usually through a working tenant of which you are admin (thus the trial tenant which you setup),

You seem to have tried to setup a trial tenant, did you manage to find a way to raise a web support ticket as an admin to that trial tenant?

No. I have tried all of the suggested support routes and still cannot create a support case or reach a human Microsoft support agent.

I am the sole Global Administrator of the affected Microsoft 365 Business Standard tenant and there is no other administrator who can restore access.

I have already:

created a temporary Microsoft 365 tenant specifically to access support;
used the Admin Centre Contact Support process;
confirmed my phone number is registered in my admin profile;
tried the listed Australian Microsoft support numbers, which either disconnect or direct me back to online support; and
exhausted the available self-service recovery options.

I now need a human Microsoft representative to help me create a service request and escalate the affected tenant to Data Protection / Tenant Recovery for ownership verification and Global Administrator recovery.

Please do not direct me back to the same telephone numbers, Admin Centre bot or self-service password reset process.
