Question

Verification E-mail Azure B2C not delivered to users

Autodidact 95

Since this morning customers signing on with our service do not receive the email with the verification code anymore. The audit logs show successful sending of the email. We were able to verify the issue and tried with different email addresses at different providers and do not receive an email as well. What is the best way to debug this issue?

We're also seeing this issue - no emails are being sent by Azure B2C.

How can we debug, or determine what is/isn't happening?

Nothing is reported on https://azure.status.microsoft/en-gb/status

Hi Autodidact

Thank you for your reaching out to the QnA community.

Unfortunately there is an ongoing issue where Azure Active Directory B2C may experience failures for email verification when trying to sign-up or sign-in to B2C applications. Password resets by end users may also experience failures. Retries might be successful. The service on which Azure Active Directory B2C relies on experienced an outage due to the faulty node.

Current Status: The dependent team is working in taking faulty node out of rotation and adding additional resources to remediate the impact

Is there a good reason why this service outage is not being reported in either Azure Service Health or the Azure Status page?

Thanks for the quick reply. It would be helpful if the issue was mentioned on: https://azure.status.microsoft/en-gb/status

How can we find out that the issue is solved? Can you let us know?

We do also receive a lot of complaints by our users for not receiving the password reset emails. Please let us know as soon as the outage is fixed.

Hi All, Just a quick update on the progress.

Current Status: As a part of mitigation strategy the dependent team fixed the unhealthy nodes and redeployed the service. The backlog data is being processed and customers should see signs of recovery.
