Hello @VKM Project,
Thank you for posting your valuable question on Microsoft Q&A forum.
I'm very sorry for the inconvenience you’ve experienced, based on the details you shared.
If you are the only administrator in your organization, this request cannot be handled through the Microsoft Q&A forum due to security and privacy limitations. As you're aware, you will need to contact the Microsoft Data Protection team, as they are the only group authorized and equipped with the necessary tools and verification procedures to confirm your identity and restore administrator access.
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
Please carefully follow this instruction to ask for Microsoft Data Protection team support:
Depending on your country or region. For some countries, when calling the support number, although there are about 30 seconds opening as something "you can visit the link...." But you can ignore this opening and wait until the option, then "1" as a business email user, "1" again for technical help.
For some countries, it will be an automated conversation like:
First, when you call the hotline, it asks what kind of problem you are worried about.
Answered: authenticator.
A: What kind of product are you using?
B: Office 365 for business.
A confirmation: education or company account?
B: For companies
A: Are you an administrator?
B: Yes.
A: Do you have the other admin in your organization?
B: No.
A: You need one.... Service request?
B: Yes
If your organization's Office 365 Business/Education subscription is from a partner or reseller, and the global administrator is unable to open a service request on your end, contact the reseller's support provider to help open a service request on behalf of you instead.
Please understand that forum moderators have no control over user accounts, especially when it comes to logging in to your account, resetting your password, changing your access, etc.
I hope Data Protection team can successfully revoke your access. If you need any further assistance or need help on any process, please feel free to reply. I'm here to help!
Thank you for your kindness and understanding so far!
