Question details
The user needs to reactivate a disabled Azure student subscription to regain access to their IoT Hub and fix Arduino MQTT connection issues.

- Product
- Microsoft Azure
- Device & OS
- not provided
- Scenario
- Attempting to connect an Arduino device via MQTT to Azure IoT Hub while the student subscription is suspended.
- Observed behavior
- IoT Hub access is suspended, and all Arduino MQTT connections fail due to the disabled subscription status.
Gather your Azure account login credentials, your subscription ID, and any specific MQTT error codes from your Arduino logs before contacting support.
Contact Azure Support for Subscription Reactivation
Since subscription suspensions are account-specific, reaching out directly to the Microsoft Azure team or posting in their official Q&A forum is the only way to restore your access.
Microsoft manages student subscription renewals and credit limits directly on their backend. You will need their engineers to review your eligibility and lift the suspension on your IoT Hub.
Log in to the Microsoft Azure Portal (portal.azure.com) using the university email address associated with your student subscription.
Click on the '?' icon in the top right corner or select 'Help + Support' from the left-hand navigation menu.
Create a new support request under 'Subscription management'. Provide your subscription ID, IoT Hub details, and the MQTT error codes to help them investigate.
Alternatively, visit the Microsoft Q&A community forums, select the Azure tag, and post your issue to get assistance from Microsoft engineers and community experts.

Manage Your Cloud Architecture Documents with WPS Office
While waiting for Azure support to reactivate your subscription, you can document your IoT Hub setups, MQTT configurations, and network architectures using WPS Office. It is a free, lightweight, and highly compatible alternative to Microsoft Office.

Frequently Asked Questions
Why was my Azure Student Subscription disabled?
Azure Student subscriptions typically expire after 12 months or when the provided $100 credit is depleted. You may need to verify your student status again with an active university email to renew it.
Will my IoT Hub data be deleted if my subscription is disabled?
When a subscription is disabled, resources like IoT Hub are temporarily suspended but not immediately deleted. You usually have a grace period (often 30 to 90 days) to reactivate the subscription before resources are permanently removed.
How can I check my Azure subscription status?
Log into the Azure Portal, search for 'Subscriptions' in the top search bar, and select it. You will see a list of your subscriptions along with their current status (e.g., Active, Disabled, or Past Due).
