Request Disallowed By Azure

Hi ATUL GUPTA,

Thanks for reaching out in Microsoft Q&A forum,

Is storage account creation restricted in Azure for Students subscriptions? If yes, what are the allowed regions or how can this be resolved? Yes, Storage Account creation is restricted in Azure for Students subscriptions, and the error you're encountering is expected behavior due to an enforced Azure Policy.

Azure for Students subscriptions have a built-in policy called "Allowed resource deployment regions" that limits where you can deploy resources, including Storage Accounts. This policy automatically blocks deployments in non-approved regions with the RequestDisallowedByAzure error you're seeing. The restriction exists to manage costs and ensure optimal service availability for free-tier accounts.

1. Identify Your Allowed Regions Go to Azure Portal > Policy > Assignments, then look for the assignment named "Allowed resource deployment regions". Open it and check the Parameters tab to see your specific allowed locations. Commonly permitted regions include East US, West US 2, West Europe, Southeast Asia, and occasionally Central US but your exact list varies by subscription. link: https://portal.azure.com/#view/Microsoft_Azure_Policy/PolicyMenuBlade/%7E/Assignments

Deploy in an Allowed Region Once you know your allowed regions, recreate the Storage Account in one of them. Avoid regions like Central India or East Asia, which are frequently blocked for student subscriptions despite geographic proximity.

If You Need a Different Region For your data engineering project, if none of your allowed regions work, you can:

1. Submit a support request via Help + support > New support request > Service and subscription limits, explaining your educational use case and requesting access to a specific region.
2. Upgrade to a Pay-As-You-Go subscription (requires a credit card) to remove all region restrictions.

This is a common hurdle for students, but once you deploy in an approved region, Storage Account creation should work without further issues.

The error RequestDisallowedByAzure - This policy maintains a set of best available regions... indicates that an Azure Policy assigned to the subscription is blocking storage account creation in the regions being selected. The policy, not the Azure for Students offer itself, is preventing deployment.

From the error type (RequestDisallowedByPolicy), the resource (storage account) does not comply with a policy definition attached to the subscription or management group. Typical examples are policies that restrict which regions can be used.

Resolution steps:

1. Identify the blocking policy
   • In the failed deployment’s error details, locate the policyAssignmentId and policyDefinitionId associated with RequestDisallowedByPolicy.
   • Open the policy definition in Azure Policy to see its description and rules. It will show which regions are allowed or what conditions are enforced.
2. Adjust the deployment to comply
   • If the policy restricts regions, create the storage account only in the allowed regions listed in the policy rule.
   • If other properties (such as public network access, SKU, or redundancy) are restricted, update the storage account configuration to match the policy rules.
3. If no allowed region works
   • If every region tried is blocked, the policy may allow only a very specific set of regions or may be misconfigured. In that case, an administrator of the subscription must either:
     • Modify or remove the policy assignment, or
     • Add exceptions/exclusions for the subscription or resource group used for the project.
4. If administrator changes are needed
   • For a student subscription managed by an institution, contact the subscription/tenant administrator and share the full RequestDisallowedByPolicy error details so they can review and adjust the policy.

The platform behavior is policy-driven: storage account creation is not inherently disabled for Azure for Students, but any assigned Azure Policy can effectively restrict it until the deployment complies with the policy rules.
