Why is the Add button disabled in Azure Email Communication Services MailFrom address? [closed]

Question

I am using Azure Email Communication Service. I have setup a custom domain, and it is fully verified (SPF, DKIK, etc.). Sending email works. However, by default it has the MailFrom set to [email protected].

I want to add my own MailFrom, e.g., [email protected]. However, the 'Add' button disabled. How do I make it enabled?

Thank you!

(I made sure the domain verification is showing all green)

TL;DR:

You need to send unspecified number of emails from [email protected] and then request increase quota using support request.

Response from Microsoft support:

ACS & ECS is currently undergoing very recent changes and the documentation is being updated.

Your ECS resource is on "Mercury" Throttling Tier/Default Tier, in said tier, now you won't be able to do the following:

1. Enable engagement tracking: How to configure user engagement tracking to an email domain with Azure Communication Service resource. - An Azure Communication Services quick start guide | Microsoft Learn

2. Add new MailFrom (sender usernames) to any domain (managed or custom), this includes Azure portal, API, CLI. If the ACS/ECS resource on the default sending limits, you can’t create new SenderUsername/MailFrom and the default sender email will be (DoNotReply@{your domain}) until the ACS/ECS on higher limit: How to add custom verified domains to Email Communication Service - An Azure Communication Services quick start guide | Microsoft Learn

The custom domain documentation is still in development, and will soon be updated.

If you'd like to add mailfrom addresses/sender usernames, you now need to upgrade your sending limits/tier. This process does not hold any costs. To increase your limits, you should start using your domain and generate some email traffic from said domain/resource, then update us by opening a support ticket with the following route "Azure/Communication Services/Assistance with Email Services/Quota Increase".
