    Hi,

    To enable +Add button (to add more MailFroms) for your custom domain you need to first increase your default email sending limit.

    There is a way to add additional MailFrom via Azure CLI (example) / PowerShell (example) without first increasing your send limit, however, I recommend you go ahead and increase your send limit regardless.

    Please carefully follow my instructions below to submit quota increase request and not get stuck in endless loop. The quota increase request is free.

    Please let me know if you have any issue creating case in a comment below and I will assist further.

    Please carefully follow instructions below to create a new Service and subscription limits (quotas) request to increase quota for Azure Communication Services.

    1. Navigate to this link to start the process:

    https://portal.azure.com/#create/Microsoft.Support

    2. Enter quota in the box and click Go

    6. Open Notepad (or other text editor). Navigate to Email quota increase article, click Copy button in upper right to copy text, and Paste it into Notepad. Add your company info to the file and answer all questions, then save to a .txt file on your computer. You will need this file later.

    7. On Additional details tab, click Enter details, select location, resource group, ACS Email domain resource, New Email sending limit you would like to request, confirm request by entering the tier enum (200, 225, 250, 275, 300, etc.) click Save and continue.

    For Azure Communication Services Email with a custom domain, the default MailFrom and display name are DoNotReply@<your-domain> and DoNotReply. To use a custom MailFrom and display name, a new sender address must be added for the custom domain.

    According to the service behavior, this is only supported for custom domains, not Azure-managed domains. After the custom domain is verified and ready, additional sender usernames (MailFrom) and their display names can be configured by following the guidance for adding multiple sender addresses. This allows changing DoNotReply to a custom MailFrom (for example, ******@deprontoinfotech.com) and setting a corresponding display name.

    If the Add button in the MailFrom addresses blade is disabled, confirm that:

    1. The domain is configured as a custom verified domain for Azure Communication Services Email.
    2. Domain verification and DNS records are fully completed so the domain is in a ready state.
    3. The account being used has sufficient permissions on the Email Communication Services resource.

    Once the domain is correctly provisioned as a custom domain and in a ready state, the MailFrom configuration (including display name) can be changed by adding additional sender usernames as described in the multiple-sender quickstart.
