@Gerry Helme I understand your concern. As an Azure customer, you received the email because Microsoft is planning to disable TLS 1.1 by default in Azure services by October 30, 2024. This means that all applications using TLS 1.1 will need to be upgraded to TLS 1.2 before that date.
Regarding your specific applications and services, you should check which Azure services you are using and then need to check your code/azure service configuration where you TLS 1.1 is still used in your code or azure service configuration. You can do this by reviewing the documentation of each service that you have created/deployed in azure. In case if you need any help with the verifying the details of individual service then I will suggest you to create a individual thread adding the specific service tag in Microsoft QnA so the team can assist you further.
In general, for your WebForms applications, you will need to check if they are using TLS 1.1. If they are, you will need to upgrade them to use TLS 1.2. This may involve updating the configuration of the application or updating the code of your web-based apps.
For your Azure databases, you will need to check if they are using TLS 1.1. If they are, you will need to upgrade them to use TLS 1.2. This may involve updating the configuration of the database or updating the connection string of your application.
For your basic VM running ReportServer, you will need to check if it is using TLS 1.1. If it is, you will need to upgrade it to use TLS 1.2. This may involve updating the configuration of the VM or updating the code of your application.
