How to open email app to specific folder PowerShell?

Question

I want to open the Windows Mail app to a specific folder within a specific account from PowerShell. Is this possible?

I learned from this post that the mail program can be launched using the custom URI ms-unistore-email:.

I can successfully launch the email app with the following PowerShell line:

Start-Process ms-unistore-email:

Of course, this simply opens the Inbox of the first account (same as if you launch the Windows Mail app from the Windows Start Menu). Is there a way to open a different account's inbox? Or even any arbitrary folder within the email account?

I tried the following, but it does not appear to work.

# This does NOT work to open the inbox of "[email protected]"
Start-Process ms-unistore-email:[[email protected]]

EDIT:

This post seems to suggest this is not possible, but is from more than 3 years ago. Is this correct?

Nothing has been changed so far. You can't navigate anywhere in the mail app using a command-line parameter. The application developers are responsible for implementing corresponding handlers, see Handle URI activation for more information on that. So, I'd suggest suggesting a feature to the product team at MS or opening a support case with MS.
