New developer experiences for Microsoft Edge

I notice that on this page to the right there are links to share the page. I also note that in common with Edge and Internet explorer, that Outlook is not one of the options. Outlook.com, Hotmail, mail for windows 10 and gmail, yahoo mail etc are there. Why isn't Outlook there? We pay for Office and this functionality should be included. It is there in Firefox. With Outlook as the default email client simply click the share email link to webpage and an outlook dialog box pops up. Perhaps is because this is chromium based, and in the Chrome browser there is only the option to share via gmail?.Elliot Kirk
