I cant attach a domain to a communication service even with it claimed.

Question

I have a claimed domain in the email communication service. I however can not add this domain to the communication service to utilize for SMTP. It does not show up in my list of available domains. Both services are in the same geographic location. If i try to add it redirects me back to the domain that is already claimed?

Hi @Blake Connon
First, make sure that the domain is properly verified.
You should have added a TXT record to the DNS settings of the domain as per the setup instructions. To double-check if Azure can read this TXT record, you can use the nslookup command in your command prompt:

nslookup -q=TXT yourcustomdomain.com

If you don’t see the expected record, Azure cannot verify the domain.

Same Geographic Location: Since both services are in the same geographic area, that should generally not be a problem, but ensure there are no regional restrictions impacting the services you are using.

Sometimes, the domain list might not refresh automatically. Try refreshing the Azure portal or logging out and back in to see if the domain shows up.

Ensure your account has the necessary permissions to add domains to the communication service. Sometimes user roles can restrict access. If you are trying to connect the domain to a service involving direct routing, ensure you've followed all configurations related to connecting domains as outlined in Azure documentation.

Hi @Blake Connon
Thank you for the update.
While your domain is verified and DKIM is correctly configured, the error message you’re seeing You need to add a verified domain in the same data location as this resource in order to proceed typically indicates that the Azure Communication Services (ACS) resource and the claimed email domain are not located in the exact same Azure region, even though both may appear to be in Brazil. Azure has multiple sub-regions within Brazil (e.g., Brazil South, Brazil Southeast), and for domain association to work, both resources must be in the same sub-region, not just the same geographic area. Please verify the exact region of both the Communication Service and the Email Communication domain from their respective “Overview” pages in the Azure Portal. If they differ, you will need to either recreate the ACS resource in the same region where the domain is verified, or re-verify the domain in the matching region.
