Thanks for the suggestion.

I do have a sound turned on for new e-mail, however, I mute my laptop
when in meetings because such a sound is disruptive, even at the
lowest volume.

I created an add-in for Outlook which can share calendar items to
other Outlook users, with or without Exchange. I may simply find the
Windows API function for waking up the screen and put something in
that tool to do this.
