There is another way, but only for Firefox and only if you use webmail: outlook.com:
Try this:
Go to "about:config", and put the value "gecko.handlerService.allowRegisterFromDifferentHost" to true.
Then in the menu choose option "Developer" and click on "Scratchpad".
Paste the following text in the editor:
javascript:navigator.registerProtocolHandler('mailto','http://mail.live.com/secure/start?action=compose&to=%s','Live Mail');
and click on "Run".
Now go to "Options", "Applications", tab content type "mailto" and select the option "Use Live Mail"
