Default modify softkey for outlook new email notify popup

Hello everyone,

First time long time, love the show.

I've tried searching for something on this and couldn't get any hits. Maybe someone here may help point me in the right direction.

Specifically I'm searching for a way to modify the softkeys that are available in the default notify pop up when a new email message is received.

The defaults are:

Desired result:
Right=Mark as Read (and to send the "mark as read" command of course not just change the text)

Device=T-Mo Wing

Hopefully I'm in the right forum, if not then my sincere apologies.

Thank you all.
