APIM "Invite user" notification email not delivered - matches issue reported in thread 5928931 and 5940191

Roger 10

Hello,

I recently created an API Management instance in the Azure portal for my company and I am not receiving the "Invite user" notification emails just like as it was described in this thread and this thread and it seems that Raskesh was able to assist in getting the issue fixed. If Rakesh or someone else can PM me, I can provide resource details to provide to the product team. I appreciate any help.

@Rakesh Mishra

Thanks,
Roger

Hi @Rakesh Mishra & @TP ,

I wanted to revisit this issue because I recently discovered that the explanation I accepted above was based on incorrect information I provided.

At the time, I believed this APIM service was on a PAYG subscription, so the PAYG email restriction appeared to explain the behavior. I have now confirmed that this was incorrect. The APIM service is, and always has been, on our CSP subscription with an Azure Plan. It has never been moved from another subscription.

Current service details:

Subscription plan: Azure Plan (CSP)

APIM SKU: Developer

Platform version: stv2.1

I also retested the issue today. I created a new APIM developer user with a Gmail address and used Invite user, but no email was received, including in the Gmail spam folder. Password-reset emails from the developer portal are also not being received.

Therefore, the PAYG restriction doesn't appear to have been the cause of the original issue after all.

Rakesh, you had previously contacted me privately requesting the APIM resource details so that you could investigate further. That private-message option no longer appears to be available on this question. Is there another secure way I can provide the subscription ID/resource information so this can be investigated?

Thanks,
Roger

Hi Roger,

As Rakesh just mentioned, please confirm your APIM instance has existed for at least 3 days since email is disabled during first 3 days after creation. I assume it has existed longer than that, but I wanted to confirm.

Please note that, they have not been explicit as to precisely which agreement types still allow email. It is entirely possible that subscription purchased through Cloud Solution Provider (CSP) is blocked as well. Azure Plan is Pay-As-You-Go pricing.

1. Have you created Technical support request through your CSP? Reason I ask is, Azure subscriptions that are through CSP are required to go through their CSP for technical support, and if the CSP can't resolve the issue they (the CSP) creates a Technical support request with Microsoft.

I'm not at all trying to discourage you from posting here on Q & A, rather, I just wanted to let you know that is one of the key limitations/requirements of CSP Azure subscriptions.

One of the ways you know you have CSP subscription is if you try to create Technical support request via Azure portal. You will get to a certain point in the process and then it will block you with text mentioning CSP and there is no ability to create the case. Also if I remember correctly if you navigate to the Help & Support screen to purchase Azure support plan it doesn't allow you to purchase one.

2. Can you take a moment and try to create support request via Azure portal? You don't need to actually create one, just get far enough in the wizard to see the CSP error so you know in fact that your subscription is categorized as being under CSP. You may use link below to start the process:

https://portal.azure.com/#view/Microsoft_Azure_Support/NewSupportRequestV4Blade/assetId/

Fill out various options, click Next. If it displays "Solutions"/suggestions, DO NOT CLICK on any of those, instead click on Return to support request in upper left corner to get back to the wizard and continue creating case. I believe the CSP error will show up on either Additional details tab or the Review + create tab. Regardless the error will show up before you have the ability to click Create button.

3. If you navigate to Cost Management + Billing in portal, then on the left menu click Settings -- Properties. On the right, under Other details, what does it have for Type?

Please reply back with your results.

Thanks.

Answer 1

Hi @Roger ,

Adding to TP's answer: the documentation has been updated since then.

What's new since TP's answer:

On paid Azure subscriptions, email is now suspended for the first three days after a new API Management instance is created. It's lifted automatically after that.

Unchanged from TP's answer:

Email is suspended for Pay-As-You-Go (PAYG) and MSDN subscriptions until further notice. This also covers built-in emails like Invite user.
Email isn't supported in Free Trial subscriptions.
Notification template customization isn't available on PAYG or MSDN subscriptions.

Since your subscription is PAYG, the PAYG restriction is what's blocking your emails. New instances on these subscription types stay blocked. Some older instances can be reviewed internally and allowed, but that doesn't apply to new instances. I don't have an ETA for when email will be enabled again for PAYG, so please watch the documentation page for updates.

If you move to a supported paid subscription and the emails still don't arrive after the first three days, please share requested information in Private messages and we'll look into it.

Hi Roger,

Which type of Azure subscription do you have? APIM email functionality is temporarily blocked for Pay-as-you-go and VIsual Studio/MSDN Azure subscriptions.

Below is excerpt from documentation:

Important

Email functionality is not supported in Free Trial Azure Subscriptions. This capability is fully blocked and cannot be enabled during the trial period.

Email functionality is temporarily suspended for Pay-As-You-Go (PAYG) and MSDN Azure Subscriptions. Email capability is temporarily disabled for these subscription types until further notice.

Notification template customization is not supported in Pay‑As‑You‑Go (PAYG) or MSDN Azure Subscriptions. These subscription types do not include the ability to modify or configure built‑in notification templates, and this limitation cannot be overridden.

Well that would explain it... I have a PAYG subscription so that lines up. I wish there was some indication about this somewhere in the service when setting it up but I guess I should have checked the documentation more thoroughly. I appreciate you letting me know. Do you have any idea as to when this may be enabled again? Thank you!
