Unable to verify domain name

Question

Hi,

I've been trying to verify our domain on a newly created tenant via DNS record, however I'm finding the same error all the time, after waiting more than three days for the DNS records for being updated and having tested all potential solutions that were answered on this forums before, I've checked the API call error and is saying the following message that isn't shown in the dashboard:

Graph call failed with httpCode=BadRequest, errorCode=Request_BadRequest, errorMessage=Domain verification failed with the following error: 'Domain REDACTED is email verifed by TenantId REDACTED. AAD B2C tenant with TenantId REDACTED is trying to take over the domian REDACTED. Taking over an email verified domain for Megatenant is not supported.

I don't know what a Megatenant is, our DNS records doesn't had any MS entry before this one as we bought the domain 1 year ago aprox. We are not sure if it might be that the previous owners had configured their Tenant with this domain, but we haven't been able to make this work.

Hello @Gabriel ,

Thanks for reaching out.

Your domain name bank####.## is verified in another email verified directory bank######.onmicrosoft.com. A domain name can only be verified in a single directory at a time.

The domain name is currently verified in a different directory (using Office 365 or other Azure services), it cannot be verified in your new directory until you perform internal or external force takeover option. When a self-service user signs up for a cloud service that uses Azure AD, they are added to an unmanaged Azure AD directory based on their email domain. For more information about self-service or "viral" signup for a service, see What is self-service signup for Azure Active Directory?

Recommended Steps

• Perform an "internal" admin takeover of an unmanaged Azure directory, you are added as the global administrator of the unmanaged directory.
• Once you become admin in unmanaged Azure directory and then try to Delete a domain name and move it to your Azure B2C directory

To know more about, refer how to take over an unmanaged directory as administrator in Azure Active Directory.

Hope this helps.
