Question

Azure API Management Developer Portal does not send any notification emails

Rainbow ai 0

Azure API Management Developer Portal is not sending any notification emails. But two days ago everything worked. Nothing was changed in two last days.

Problem:

User signup works and creates a developer account.
The user remains in Pending state.
Confirmation email is never received.
Password reset email is also never received.
The issue happens both on custom portal URL and default portal URL
Notification templates exist, including: ConfirmSignUpIdentityDefault, PasswordResetIdentityDefault, InviteUserNotificationMessage
Activity Log shows no visible errors.

Hi @Rainbow ai ,

As per the latest update received from APIM team, the following limitations that were recently imposed due to internal operational requirements:

Email functionality is not available in Free Trial, Pay-As-You-Go, MSND and MSDNDevTest Azure Subscriptions

It is not possible to change/relax the above mentioned limitations. Customers can change the billing model of their Azure subscription if they wish to utilize the complete functionality without restrictions.

In subscriptions other than Free Trial, Pay-As-You-Go, MSND and MSDNDevTest, email functionality is not available for first 3 days after service creation of Classic SKU services (SKUV1). Email functionality should start working after 3 days.

hi & thx for sharing urs issue here at Q&A portal,

If signup works but confirmation + password reset emails both stopped, this is prob APIM notification delivery, not the developer portal URL. The fact it fails on both custom portal and default portal matters. That rules out most custom-domain/frontend issues. The user being stuck in Pending means APIM created the account but the identity email flow didn’t complete. check APIM notification settings and identity templates. Make sure the templates are enabled and not empty, esp

ConfirmSignUpIdentityDefault

PasswordResetIdentityDefault

InviteUserNotificationMessage

https://learn.microsoft.com/en-us/azure/api-management/api-management-howto-configure-notifications

Then test w/ an external mailbox like Gmail/Outlook.com. If external gets it but corporate mail doesn’t, it’s mail quarantine/filtering. Check Exchange/Defender quarantine too. APIM default sender can get filtered and it’ll look like APIM never sent anything. If no mailbox gets anything, it’s likely APIM-side mail delivery or a service issue. Activity Log usually won’t show mail send failures, so no Activity Log error doesn’t prove emails were sent. If APIM is in VNet/internal mode, check outbound requirements too. APIM still needs required outbound access for platform deps.

https://learn.microsoft.com/en-us/azure/api-management/virtual-network-reference

Support ticket should include APIM service name, region, SKU, portal type, timestamp in UTC, test user email, affected templates, and note that signup creates Pending users but both confirm signup and password reset emails are missing.

Short version: verify templates + try external mailbox + check quarantine. If nothing arrives anywhere, ask MS to confirm whether APIM attempted to send the emails from backend.

rgds,

Alex

Hi Alex,

Thank you for your response.

I have already verified all of the items you mentioned.

I also tested multiple recipient mailboxes (including external mailboxes), and no notification emails are delivered at all.

Because signup confirmation, password reset, and invite emails all fail, and the behavior is identical on both the default and custom developer portals, I suspect the issue is in the APIM notification service rather than the Developer Portal configuration.
