Question

Communication Services: Request for Email Quota Increase — Transactional Invoicing Emails

Pierre Sevrain (CELAD) 0

Problem description

I am requesting an increase in the email sending quota for my Azure Communication Services resource to support production workloads. The current setup involves a custom domain used for transactional invoicing emails, with a need to send approximately 100 messages per minute, 1000 per hour, 5000 per day (high peaks are possible in our case). The case was initiated to facilitate this increase.

Environment

Azure Communication Services Email in a production Azure subscription with a custom domain notif.***., used for transactional invoicing emails.

What I've already tried

I have reviewed the case notes and supporting guidance. I confirmed that DKIM2 is in Verified status, and SPF, DKIM, and domain ownership are verified in the Azure Portal.

Current status

I'm stuck for 3 days now in an email ping-pong with an AI that keeps asking the same questions in loop without understanding the request.

Does anyone have a clue on how to get a quota increase, please ???

Thx

@for other people experiencing the same problem:

The process and the screenshots proposed here do not match what I actually see on the portal. Useless.

Following my post I was joined directly (mail) by a member of Microsoft support team who processed the request seriously. (after repeating all info a last time)
