Unable to Verify Custom Domain Name

Hello -

We are trying to add our custom domain name into AAD so we can begin to use Single Sign-On with AD Connect. The verification process will not complete. The required TXT records are in place. I think this is because our domain is a subdomain - we do not own or have access to the parent domain (government agency) and the parent domain does appear to already be registered within Azure. How are we able to get this process to complete?

Error is "Failed to verify domain name"

We have a basic subscription so I am unable to enter a support case for this issue.

    Hi @Kevin Foster

    Thank you for asking this question on the **Microsoft Q&A Platform. **

    Unfortunately, you can add a subdomain.

    If you want to add a subdomain name such as ‘europe.contoso.com’ to your organization, you should first add and verify the root domain, such as contoso.com.

    Hope this helps,

    I had the same, or a similar problem.

    I created the MX and TXT records as directed, but the domain kept failing to verify.

    The issue was I still had the domain verified in my old Azure AD org. I deleted it, updated the TXT and MX records, and it worked. Either it just took an hour to detect the new DNS records, or the domain being claimed elsewhere in Azure AD was borking it. Good luck.
