Welcome to the Microsoft Q&A forum.
Thank you for contacting us. I would like to provide you with the following information:
I noticed that you mentioned you cannot create a support ticket due to the complex process. I understand that going through multiple steps can be frustrating. However, removing a tenant from the system can only be done from the backend. I kindly ask for your understanding.
You can follow these steps to create a ticket:
Step 1: Go to https://admin.microsoft.com using your Global Admin account.
Step 2: Click on Help and Support.
Step 3: Enter the title: Need assistance deleting tenant.
Step 4: Click on Contact Support.
Step 5: Choose your preferred contact method.
Once your ticket is received and assigned to an agent, the agent will proactively reach out to you and assist with deleting the tenant.
Note: As a moderator, I can only guide you through the basic steps to reach the right department that can best support you. That department has the tools to perform the tenant deletion from the system side.
I hope this information is helpful.
If you have any questions or need further assistance, please feel free to share them in the comments on this post so I can continue to support you.
I look forward to continuing the conversation.
