I have an active Azure Developer support plan with Priority Community Support.

I need help from a Microsoft Azure / Microsoft Entra engineer.

Goal: I want to verify the custom domain realsum.co in Microsoft Entra ID so I can create and use user accounts with the @realsum.co domain.

Important: The DNS for realsum.co is NOT hosted in Azure. It is managed by an external DNS provider.

Issue: Microsoft Entra ID gives me a TXT record to verify the domain. I add that TXT record in my external DNS provider, but Microsoft Entra still does not verify the domain.

Please help me confirm:

Whether realsum.co is already associated with another Microsoft Entra tenant. Whether there is a tenant-side block or ownership conflict preventing verification. Whether the TXT record expected by Microsoft Entra is correct. Whether the TXT record must be created at the root domain / @ host or with a different host/name value. What exact DNS record I must create so Microsoft Entra can verify realsum.co. What exact steps I must follow to verify or release the domain.

This is blocking my ability to create Microsoft Entra users and accounts using @realsum.co.

If tenant-level or domain ownership investigation is required, please escalate this case to a private Azure support ticket.
