Please try v4.5.10.9 beta.

I don't use Outlook, but it sounds like something that has to be implemented/fixed in the program itself.

I have checked it on my Windows 10 PC, and it starts as expected.
Do you see 7+ Taskbar Tweaker in the startup list? Perhaps it was mistakenly disabled?

Your request was implemented in the latest beta version, 4.5.10.7.

Do you mean that dragging with the right mouse button does nothing unless you uncheck and re-check the option?


Do you have a way to reproduce it?

Note that there's the scroll_maximize_restore advanced option, which allows to do what you're asking for by using the mouse wheel.

Unfortunately, I am having trouble finding a way to identify the window of the Taskbar button that has been clicked (I cannot get its handle), so I have not been able to write an AHK script to do that.

You might want to try using 7+ Taskbar Tweaking Library :)

I will add maximize/restore in the next version. That's not exactly what the OP asks for, though: he asks for one hotkey to be able to toggle between maximized/restored state, as far as I understand.
