Hi @Munira ActiveServers,
Thank you for providing the detailed background and context.
I noticed that you included a ticket number in your post. Before proceeding, could you clarify where this ticket was created and through which Microsoft support portal or website it was submitted?
The reason I ask is that the ticket number format doesn't appear to match what I would typically expect for a Microsoft 365 Business support case. If possible, could you please double-check the ticket number and send the full details via private message in case any digits are missing?

In the meantime, for similar situations, you would typically need to open a support request directly through the Microsoft 365 Admin Center, as domain release requests require involvement from Microsoft's support team. If you already have full administrative access to your new Microsoft 365 tenant, you can submit a support case by following the guidance below: Get support - Microsoft 365 admin | Microsoft Learn

Tips: You can switch off the Support Assistant as shown in the screenshot, then type a few short characters into the search box and select Get Help. After that, wait for the Contact Support button to appear and click it. At the final step, be sure to clearly describe your request in the description fields so the support engineers can quickly understand your issue and assist you more effectively.
Once the support ticket has been submitted, it will be assigned to a Microsoft Technical Support Engineer. They may ask for documentation to verify ownership of the domain and better understand the circumstances surrounding the previous tenant. After reviewing the information, they can arrange a remote support session if necessary and work with you through the appropriate validation, ownership verification, and recovery processes required to address the request. If eligibility and ownership requirements are met, they will be able to advise on the available options for recovering access or releasing the domain from the old tenant.
Just to set expectations, this is a community-driven user-to-user forum, and I am not part of the Microsoft Data Protection team or any internal Microsoft support organization. I also do not have access to Microsoft's backend systems and cannot directly release domains, modify tenant configurations, or escalate cases on your behalf. However, I hope this guidance points you to the correct support channel that can properly review and process your request.
Thank you again for taking the time to post your question. I wish you the very best with the process, and I hope you're able to get the domain successfully released and moved to your current tenant as smoothly as possible.
