Hello Bhaskar Palnati

Thank you for reaching out via the Microsoft Q&A forum.

Regarding your question, there are two methods you can try:

1> Contact Support via Phone. When you reach an agent, kindly explain that your tenant is currently blocked and you do not have access to it. Request that the agent create a support ticket on behalf of the blocked tenant, as you are unable to do so yourself. To prevent similar issues in the future, I strongly recommend assigning at least two Global Administrators to your Microsoft 365 tenant with different authentication methods. This ensures that if one admin is locked out or unavailable, the other can still manage and recover access to the account.

2> Set up a temporary Microsoft 365 tenant using a trial license: Microsoft 365 Business Plans and Pricing | Microsoft 365 Click Try for free to set up a temporary Microsoft 365 tenant with a trial license.

Use this new account to sign in to the Microsoft 365 Admin Center and submit a support request on behalf of your primary (locked) account. Navigate to Help & Support > Create a support request. This temporary account is only needed for submitting the request and can be deleted afterward to avoid any charges. When the agent contacts you, please inform them that your previous tenant is currently blocked and you do not have access to it. Kindly request that the agent create a support ticket on behalf of the blocked tenant, as you are unable to do so yourself. You might consider turning off Support Assistant in the Microsoft 365 Admin Center to avoid automated troubleshooting loops. Please note that the process can take up to 20 business days, as the Data Protection team has a significant workload.

I hope the details provided will assist you effectively
