When setting up an Event Grid Partner Topic, the Transport Layer Security option only provides selection for TLS up to 1.2.

If I change my web app to require TLS 1.3 the subscription stops working.

When will event grid partner topics be updated to enable TLS 1.3 so that I can update my web applications as well?

    Hello ,

    Currently, Azure Event Grid supports TLS 1.2 as the default for public endpoints, with TLS 1.0 and TLS 1.1 still available for backward compatibility. However, there is no specific information available about when TLS 1.3 will be supported for Event Grid Partner Topics. You can find more details about TLS support in Azure Event Grid in the official documentation.

    Pls check and let us know if any further ques

    Thanks
