How do I request an Azure email sending quota increace.

Question

We are on the Microsoft Sponsorship Azure free tier.

The documentation says we can increase an increase in our Azure smtp sending limits, which is done by raising a ticket.
Raising a ticket on the free tier is limited to billing and quota increases.
However the system will not let me raise a ticket, it says I need to pay for support.

Please can you advise how to do this?

Hi @Ian Mellor

This behavior is expected for free/sponsorship subscriptions.

Azure email sending (SMTP/ACS) limits are controlled via quotas, and increasing them requires submitting a quota request. However, Microsoft documentation confirms that free or trial-based subscriptions are not eligible for quota increases, which is why the portal is prompting for a paid support plan.

To proceed, you’ll need to upgrade your subscription to Pay-As-You-Go, after which you can submit a quota increase request from the Azure portal using the standard process.

Reference :

https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/azure-subscription-service-limits#managing-limits

Just to make sure I’m providing the right guidance, could you confirm the following:

• What is the subscription type (Free, Sponsorship, Pay-As-You-Go)?
• Are you using Azure Communication Services Email or another SMTP setup?
• At which step are you being prompted to purchase a support plan (screenshot if possible)?

Answer 2

For Azure Communication Services (ACS) Email, quota increase requests are supported on paid subscriptions and are submitted as Service and subscription limits (quotas) support requests. The documented path is:

1. Go to the Azure portal support creation page: https://portal.azure.com/#create/Microsoft.Support.
2. In the search box, type quota and select Go.
3. Choose Others / Service and subscription limits (quotas) and continue.
4. Set:
   • Issue type: Service and subscription limits (quotas)
   • Quota type: Azure Communication Services Email: Sending Limits
   • Select the correct subscription (the Microsoft Sponsorship subscription) and proceed.
5. On Additional details:
   • Select the region, resource group, and the ACS Email domain resource.
   • Enter the New Email sending limit and confirm the tier enum (for example: 200, 225, 250, 275, 300, etc.).
6. From the Email quota increase article, use the “Copy” template text, fill in the requested business and usage details, save it as a .txt file, and upload it in the File upload section.
7. Complete the remaining fields and submit the request.

If the portal is still forcing a paid support plan instead of allowing the free Service and subscription limits (quotas) flow, that behavior is outside what is described in the documentation and requires direct Azure Support intervention via the same support entry point.

Note that before requesting a higher send limit, ACS Email requires:

• Using a custom domain (not the Azure-managed test domain).
• Building a good sender reputation (low failure and spam rates) by sending legitimate production traffic.

These factors are considered when the quota increase request is reviewed and are required for approval.
