The idMso for that control is logically enough "InviteAttendees".
What do you want to do with that control?
If you want to "click" it call
Inspector.CommandBars.ExecuteMso("InviteAttendees").
You can also find out if it's enabled, the image, label, pressed status,
screentip, supertip and visibility. Look at the Object Browser for
CommandBars and check out everything listed as *Mso, where * is all the
beginnings of the methods.
