If the key doesn't open Thunderbird open Control Panel > Default Programs > Set your default programs, click Thunderbird in the list, click "Choose defaults for this program" and make sure both MAILTO and Send Mail are checked, if not check them and click save then try your key again.
This is basically what Alpha said above.
You could just click "Set this program as default" for Thunderbird as it only has these two options and two for it's own file types. You won't have to do anything if it says "This program has all of it defaults".
Let us know if if your key opens it when it is the default for both protocols.
And do you have any other e-mail clients installed you wish to use at any time?
If Thunderbird opens with the key are you happy enough to setup your GMail and Hotmail accounts in it and use that as your solution?
