Good day,

I hope a Microsoft moderator sees this, because I have exhausted all other possible support options and am completely stuck.

The situation is as follows:

  1. I'm the only Global Administrator of my Microsoft 365 Business tenant.
  2. I was locked out of this business account due to an MFA (error code 500121) issue after getting a new phone.
  3. My email address is registered as both a personal and a business account. This causes an identity conflict that blocks any login attempt, even for managing my personal account.
  4. All support channels are inaccessible to me:
  • The online support on the website requires me to log in, which is exactly the problem.
  • The official business support line in the Netherlands ([020 500 1500]) is automatically hung up after a referral to the website.

I know the only solution is for the Data Protection Team to reset my MFA settings for the corporate account. However, there is literally no way for me to contact and start this process.

Can a moderator please escalate this internally and make sure I am contacted to create a support case?

    Hi @Parker Diana,

    Thank you for posting your question in the Microsoft Q&A forum.      

    I’m very sorry to hear about your situation. Regarding that you’re unable to log in to your global admin account.  

    May I ask that do you have another admin account or is there any other admin in your organization? 

    If you don't have any other admin account in this situation, the Microsoft Data Protection team has tools and processes in place to verify identity and regain access to administrator accounts.    

    Please note that I'm also a user I have no control over user accounts, especially when it comes to logging in to your account, resetting your password, changing your access, etc. 

    You can try set up a new trial tenant and submit your support request:   

    1. Visit the Microsoft 365 Enterprise Plans page: Go to Compare Office 365 Enterprise Pricing and Plans | Microsoft 365.   
    2. Choose a plan and start a free trial: Select any of the available plans and click "Try for free" to begin the trial setup process.   
    3. Follow the guided setup: Complete the steps to create a new Microsoft account and a new tenant. This will be a separate and independent Microsoft 365 environment.   
    4. Access the Microsoft 365 Admin Center: Once the new tenant is created, navigate to https://admin.microsoft.com/
    5. Go to Support: In the left-hand navigation menu, click on "Support" and then "Help & support."   
    6. Raise a support ticket: Describe your issue in detail. Crucially, you must clearly state that you are locked out of a different, pre-existing Microsoft 365 tenant where you are the administrator. Provide the following information about your locked account:    
      • Your administrator account email address for the locked tenant.   
      • The domain name of your locked tenant    
      • Any error messages you are receiving.   
      • Details about the authentication issues you are experiencing.   
      • Confirmation that you are the administrator of the locked tenant.   
    7. Submit your ticket: Follow the prompts to submit your support request. You will likely receive a ticket number for tracking.   

    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.

    Important notes:    

    • This new trial tenant will not give you access to any of the data or settings in your original locked tenant. It is solely a temporary means to contact Microsoft support.   
    • Be prepared for Microsoft support to ask for verification of your identity and administrative rights for the locked tenant.   
    • The resolution time might be longer as you are contacting support from a different tenant.   
    • Remember to cancel the trial subscription for the new tenant once your issue with the original account is resolved to avoid any unintended charges. You can typically do this within the Microsoft 365 Admin Center under "Billing" -> "Your products."      

    Thank you again for your time and understanding.  I really appreciate your patience, and I’m here to help. Looking forward to your response.
