Not getting Activated Severity email notifications for alert

Question

We are experiencing an issue with Azure Monitor alerts across multiple services in our subscription. Previously, the alerts were working as expected — both the "Activated Severity" and "Deactivated Severity" email notifications were being received correctly. However, recently

we have observed the following behavior:

• Only "Deactivated Severity" alert notifications are being received via email.
• "Activated Severity" alert emails are no longer being triggered, even though the alert condition is met and the issue is active.

We have verified the following:

• Action groups are correctly configured with email receivers.
• Email addresses are verified and active.
• Alert rules are still valid and threshold conditions are being met.
• Test notifications from action groups do reach the configured email addresses.

Despite this, Activated Severity emails are not received, which is critically affecting our monitoring and incident response processes.

Dear Muhammad Fahad,

Thank you for reaching out and sharing your question on the Q&A portal.

Based on your description, it seems that the "Activated Severity" email notifications are not being delivered, while the "Deactivated Severity" notifications are working fine. This can indeed impact your ability to respond to incidents promptly. Let’s break down the possible causes and solutions in a simple way.

First, since you’ve confirmed that the action groups are correctly configured and the email addresses are verified, the issue might not be with the setup itself. However, it’s worth double-checking the alert rules to ensure that the "Activated" state is properly configured to trigger notifications. You can review the alert rule configuration in the Azure portal to confirm this. For more details, refer to the Microsoft documentation on creating alert rules: Azure Monitor alert rules.

Another possibility is that there might be a delay or a temporary issue with the email delivery service. Azure Monitor relies on action groups to send notifications, and sometimes delays can occur. You can test the action group again to see if the issue persists. If the test notifications work but the actual alerts do not, this could indicate a problem with the alert rule’s condition or the way it evaluates the "Activated" state.

Additionally, check if there are any filters or routing rules in your email system that might be blocking or diverting the "Activated Severity" notifications. Sometimes, email servers or spam filters can interfere with the delivery of certain messages.

If the issue continues, you might want to review the activity logs for the alert rules to see if there are any errors or warnings. The activity logs can provide insights into whether the alerts are being triggered but not delivered. For guidance on using activity logs, see: Azure Monitor activity logs.

Lastly, if none of these steps resolve the issue, consider reaching out to Azure Support for further investigation. They can help identify any underlying problems that might not be immediately visible.

Thank you again for bringing this to our attention. We hope this information helps you resolve the issue. If you have any further questions or need clarification, please don’t hesitate to ask.

Best regards,
Alex
