Open mail taskbar icon in Windows 10

In Win 7, the taskbar icon for an open email was an envelope, which distinguished it from the actual app, whose icon was the em Client logo. Now in Win 10, open emails also appear as the logo instead of the envelope.
Is there a way to get open emails to show up with the envelope icon as in Win 7?

Not seeing that Stacy. On a default Windows 10 setup (no customization or changes to settings) it appears as you are asking for.

Maybe you changed some settings in Windows?
