Since upgrading to Windows 10 1709, the snipping tool 'send snip' button does not work. Instead of opening Outlook 2016, it give me an error message of 'The snip could not be sent. Check that an email program is installed and then try again.' Outlook 2016 is the default mail app and the app selected for the mailto protocol. HTML mailto links and the Email button in the Word 2016 Quick Access toolbar work as expected.
