Hello Caio Caetano,
Welcome to Microsoft Q&A!
It sounds like you're encountering a permissions issue when trying to add a new MailFrom address in Azure Email Communication Service. Here are a few steps you can try to resolve this:
- Verify Permissions: Ensure that your Azure role assignment includes the Email Communication Services Contributor role or higher. You can check this under Azure Portal → ACS → Access Control (IAM) → Role Assignments
- Use REST API or CLI: If the portal is giving you trouble, try creating the MailFrom address using the REST API or Azure CLI. This method has worked for others facing similar issues
- Check Data Location: Make sure that both your Azure Communication Services and Email Communication Service have the same data location. Mismatched data locations can cause issues
- Refresh and Retry
If what I mentioned does not work, then this problem seems to be due to an "email quota" limit so it is only solved by creating a support request through the Azure portal. And you can use this template to create the support request: Request an email quota increase
In case you need the information used as a reference: https://learn.microsoft.com/en-us/answers/questions/2153851/unable-to-add-multiple-mailfrom-addresses-on-azure (This user's response mentions the department you can refer to which is "Quota request for Cloud Services"), https://learn.microsoft.com/en-us/answers/questions/1630281/add-button-disabled-in-email-communication-service.
Hope the information is helpful!
Regards,
Gao
