file association - "Send to: Mail recipient" context menu not working

I have set the Mail app from Microsoft (WinRT) as the default application for mail in Default Programs. However, when I right-click on a file, and select Send to > Mail recipient I get a message box saying:
There is no email program associated to perform the requested action. Please install an email program or, if one is already installed, create an association in the Default Programs control panel.

Is there a way to get this action working with Mail?

Answer

The Send to ... Mail Recipient uses the MAPI\Send Mail association, or the Send mail command.

The Microsoft Mail app only contains an association for the MAILTO protocol, so you can't set it as a recipient of the Send mail command.
