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.
let me know if you have any further assistances.
