Hi @Mihai Mihaiescu,

If your DKIM configuration is correct but not passing validation in Azure Communication Services, you can follow these troubleshooting steps:

Use the "nslookup" command to check if the DKIM records are correctly set up. Run the following command in your command prompt:

nslookup set q=TXT
   selector1-azurecomm-prod-net._domainkey.yourdomain.com
   selector2-azurecomm-prod-net._domainkey.yourdomain.com

Replace yourdomain with your actual domain name. Ensure that the output includes the expected CNAME DKIM records.

If the "nslookup" command does not return the expected CNAME records, it indicates that Azure Email Communication Service cannot verify the DKIM status. You may need to revisit your DNS settings on Namecheap to ensure that the DKIM records are correctly added.

DNS changes can take time to propagate across the internet. Although it often happens within an hour, it can sometimes take up to 48 hours. It's advisable to wait and then reattempt validation in the Azure portal after this period.​
