We are an ISV and as part of our solution we create Azure Service Bus namespaces that our customers will sometimes integrate with. With the recent changes to certificate authorities (https://learn.microsoft.com/en-us/azure/security/fundamentals/tls-certificate-changes) that has occurred we have learned that some of our customers are doing certificate pinning in their code they have written to integrate with the Service Bus namespace that we run as part of the solution. Because we are the owner of that resource and not our customer we were the only one to receive an email notifying us about possible actions that needed to be taken due to the change in certificates.
Our customer that was affected by this certificate change is now asking us if there is any way for them to be on the email notification list for future changes that may affect them in future.
Does anybody know how to go about requesting to be on the email distribution list for Azure change notification like the one above without the customer spinning up their own Azure subscription? Is this possible or will we need to find a way to forward all such emails on to our customers?
