My tech support died and email [Moderator note: Personally Identifiable Information removed]@intmedwaterloo.com cancelled. As administrator I cannot access ms 365 subscription without changing my credentials and cannot make that happen.

    Dear Robert,

    First of all, I'm truly sorry to hear about the loss of your tech support person. That is difficult enough on its own, and having to deal with being locked out of your administrator account on top of it must be genuinely stressful. As a forum moderator, I genuinely wish I could directly reset the credentials on your account for you. Unfortunately, my role here is limited to providing general guidance and steps you can apply from your side. I am not able to reset MFA, recover admin access, or make changes to your Microsoft 365 tenant. That said, I will do my best to provide a clear path forward.

    Since you are the sole administrator and the associated email address has been cancelled, this will need to be handled by the Microsoft Data Protection team. They have the tools to verify your identity and ownership of the tenant, and to help you regain administrative access. For business accounts, the best way to reach them is by phone. You can refer to this article to see the customer support phone number for your region. 

    Customer service phone numbers - Microsoft Support 

    Here are some tips and a sample response to help you navigate the Interactive Voice Response (IVR) system more effectively: 

    In some countries, this is an automated conversation; For example, when you call the support line, you will be asked the following: 

    IVR: What kind of problem do you have? 

    You: Account recovery

    IVR: What kind of product do you use? 

    You: Office 365 for business. 

    IVR confirmation: education or business account? You: For Business 

    IVR: Are you an administrator? 

    You: Yes. 

    IVR: Is there another administrator in your organization? 

    You: No. 

    IVR: Do you need a... service request? 

    You: Yes, please connect me with the Data Protection team. 

    Kindly note that you may need to repeat this process a few times, availability can vary based on local business hours, and the term "Global Admin" should be clearly mentioned during the call. 

    Alternatively, if reaching support by phone is not possible, you can also create a free trial tenant and submit your request from there. To set up a new tenant, follow these steps: 

    Visit the Office 365 Enterprise plan and pricing comparison page, choose Basic plan, and click "Try for free" to start a free trial. 

    Follow the guided setup process to create your new trial account. 

    Once the new tenant is created, you should be able to access your support portal and submit your ticket. 

    Sign in to the Microsoft 365 admin center 

    Go to Show All > Support > New Service Request

    In the request, explain your situation in detail. 

    The support team will guide you through the identity verification process to help you regain access to your account. 

    Important Notes: 

    This new test tenant doesn't give you access to your original locked tenant's data or settings. It only serves as a temporary means of contacting Microsoft support. 

    Be prepared for Microsoft to want to verify your identity and admin privileges from the previous tenant. 

    The processing time may be longer due to contacting support from another tenant. 

    Remember to cancel the trial subscription as soon as your original account is restored to avoid unwanted charges. You can do this in the Microsoft 365 admin center, under Billing > Your products. 

    I truly hope you get this resolved swiftly. Please know that even though I cannot directly intervene, pointing you toward the correct, specialized support is genuinely the most effective help I can offer from my position. Please let me know if you need anything else. Wishing you all the best.
