Verification E-mail Azure B2C not delivered to users

Question

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?

Hi Karl,

Thank you for contacting Q&A Forum. I would like to provide my findings and proposed solution:
This issue has been reported by multiple users and is likely due to a service disruption or outage in the backend systems that Azure B2C relies on

Here's what you can do to debug and mitigate the issue:

1.Check Azure Service Health:

Go to the Azure Service Health dashboard in your Azure portal.

Look for any active incidents related to Azure Active Directory B2C or email delivery in your region.

2.Retry the Operation:

Some users have reported that retries may succeed intermittently. This suggests partial service degradation rather than a complete outage.

3.Check Spam/Junk Folders:

Although unlikely if you've tested across providers, it's still worth confirming.

4.Use Custom Email Providers:

If you're using the built-in email provider, consider switching to a custom provider like SendGrid or SMTP temporarily. This gives you more control and visibility into email delivery.

5.Enable Diagnostic Logs:

Use Azure Monitor to track email delivery attempts and failures.

Look for logs under Audit Logs and Sign-in Logs for more granular details.

6.Open a Microsoft Support Ticket:

If the issue persists and is not acknowledged on the Azure Status page, open a support ticket from your Azure portal. This ensures your case is tracked and escalated appropriately.
Kindly let me know if this work for you and please let me know if you have any further question.
