Windows 10 - how to open mailto links with Thunderbird Portable?

Job ID: 30787968

Budget: €8 – €30 EUR

It sounds like a very dumb question: How can I configure Thunderbird Portable to open mailto Links in Windows 10. Of course, I associated the MAILTO protocol and the default email app with Thunderbird. But it does not work. Simple as that. Can anybody help? Both Windows 10 and Thunderbird are the latest builds
